Overview of the Routers

Cisco Integrated Services Routers Generation 2 (ISR G2) offer data functionality through Gigabit
Ethernet ports and security functionality with a virtual private network (VPN) accelerator on the
motherboard. Additional security features are available with add-on hardware and software.
Cisco 2900 series and Cisco 3900 series routers also provide voice IP telephony with digital signal
processor (DSP) capability; and voice gateway, DSP farm, IP-to-IP gateway, Cisco Unified
Communications Manager Express (CUCME) via Cisco IOS. Cisco Unity Express (CUE) is provided
through the use of add-on hardware.
This series of ISRs have new slots that support next generation Enhanced High-Speed WAN Interface
Cards (EHWICs), Internal Services Modules (ISMs), Packet Voice Data Modules (PVDM3s), Service
Modules (SMs), and Services Performance Engines (SPEs).
Access to the Cisco Multi-Gigabit Fabric (MGF) facilitates connection between switch ports on the ISR
without utilizing all of the external ports. A logical GE interface on the ISR connects external and
internal modules through the MGF for improved LAN and WAN switching.

Chapter 2 Preparing for Router Installation Safety Recommendations • Locate the emergency power-off switch in the room in which you are working. Caution For the safety of your equipment. ensuring that it makes good skin contact. Always follow ESD prevention procedures when removing and replacing modules: • Ensure that the router chassis is electrically connected to ground. such as moist floors. • Never assume that power is disconnected from a circuit. It can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. send another person to get medical aid. • Use caution when installing or modifying telephone lines. • If no wrist strap is available. If an electrical accident occurs. frayed power cords. • Disconnect all power before doing the following: – Installing or removing a chassis – Working near power supplies • Look carefully for possible hazards in your work area. – Turn off power to the device. – Determine if the person needs rescue breathing or external cardiac compressions. the wrist strap and cord must operate effectively. • Do not work alone if hazardous conditions exist. It should be between 1 and 10 megohms (Mohm). proceed as follows: – Use caution. assess the condition of the victim and then call for help. Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. • Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface. you can quickly turn off the power. and missing safety grounds. Otherwise. ground yourself by touching a metal part of the chassis. Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. use the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone wiring or other network cabling: • Never install telephone wiring during a lightning storm. In addition. periodically check the resistance value of the antistatic strap. To guard against ESD damage and shocks. ungrounded power extension cables. Cisco 2900 Series and 3900 Series Hardware Installation Guide 2-4 . – If possible. • Wear an ESD-preventive wrist strap. • If an electrical accident occurs. • Never install telephone jacks in wet locations unless the jack is specifically designed for it. then take appropriate action. do not become a victim yourself. • Never open the enclosure of the internal power supply. Always check.

The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. If the chassis is installed on slides.Chapter 2 Preparing for Router Installation General Site Requirements General Site Requirements This section describes the requirements your site must meet for safe installation and operation of your router.

The following information can help you plan your equipment rack configuration: • Allow clearance around the rack for maintenance. inadequate ventilation. • Ensure that the room where your router operates has adequate air circulation. this section can also help you isolate the cause of failures and prevent future problems. ambient air temperature may not cool equipment to acceptable operating temperatures. optional larger brackets for use with a 23-inch rack. these precautions and recommendations may help you isolate the cause of failure and prevent future problems. and can make maintenance difficult. If you are experiencing shutdowns or unusually high errors with your existing equipment. interface card slots. Electrical equipment generates heat. • When mounting a chassis in an open rack. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above it. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment. The chassis is designed to allow cooling air to flow within it. ensure that the rack frame does not block the intake or exhaust ports. refer to the “General Site Requirements” section on page 2-5. Ensure that the rack is not congested. check the position of the chassis when it is seated in the rack. • Ensure that the chassis cover and module rear panels are secure. Router Environmental Requirements Cisco 2900 series routers can be placed on a desktop or installed in a rack. Ensure that the site is properly prepared before beginning installation.

Connecting WAN, LAN, and Voice Interfaces
This section describes how to connect WAN, LAN, and voice interface cables. It covers the following
topics:
• Ports and Cabling, page 3-43
• Connection Procedures and Precautions, page 3-44

Note One or two Ethernet cables are typically provided with the router. Additional cables and transceivers can
be ordered from Cisco. For ordering information, contact customer service. For cable pinouts, see the
Cisco Modular Access Router Cable Specifications document.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first. Statement 1026

Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect Gigabit Ethernet ports using RJ-45 connectors for shielded twisted pair cable only to
intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield
must be grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be
metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed
for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue
4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not
sufficient protection in order to connect these interfaces metallically to OSP wiring.

Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations. Statement 1036

Specifying a Default Route or Gateway of Last Resort
This section describes how to specify a default route with IP routing enabled. For alternative methods of
specifying a default route, see the Configuring a Gateway of Last Resort Using IP Commands tech note.
The Cisco IOS software uses the gateway (router) of last resort if it does not have a better route for a
packet and if the destination is not a connected network. This section describes how to select a network
as a default route (a candidate route for computing the gateway of last resort). The way in which routing
protocols propagate the default route information varies for each protocol.

Configuring IP Routing and IP Protocols
For comprehensive configuration information about IP routing and IP routing protocols, see the Cisco
IOS IP Routing Protocols Configuration Guide, Release 12.4T on Cisco.com at the following URL,
http://www.cisco.com/en/US/docs/ios/iproute/configuration/guide/12_4t/irp_12_4t_book.html.

IP Routing

You can configure integrated routing and bridging (IRB) so the router can route and bridge
simultaneously. The router will act as an IP host on the network whether routing is enabled or not. To
read more about IRB see the following URL on Cisco.com,
http://www.cisco.com/en/US/tech/tk389/tk815/tk855/tsd_technology_support_sub-protocol_home.html
IP routing is automatically enabled in the Cisco IOS software. When IP routing is configured, the system
will use a configured or learned route to forward packets, including a configured default route.

Note This task section does not apply when IP routing is disabled. To specify a default route when IP routing
is disabled, refer to the Configuring a Gateway of Last Resort Using IP Commands tech note on
Cisco.com.

Default Routes
A router might not be able to determine the routes to all other networks. To provide complete routing
capability, the common practice is to use some routers as smart routers and give the remaining routers
default routes to the smart router. (Smart routers have routing table information for the entire
internetwork.) These default routes can be passed along dynamically, or can be configured into the
individual routers.
Most dynamic interior routing protocols include a mechanism for causing a smart router to generate
dynamic default information that is then passed along to other routers.

Default Network
If a router has an interface that is directly connected to the specified default network, the dynamic
routing protocols running on the router will generate or source a default route. In the case of RIP, the
router will advertise the pseudonetwork 0.0.0.0. In the case of IGRP, the network itself is advertised and
flagged as an exterior route.
A router that is generating the default for a network also may need a default of its own. One way a router
can generate its own default is to specify a static route to the network 0.0.0.0 through the appropriate
device.

Chapter 4 Configuring the Router
Performing the Initial Configuration on the Router

Gateway of Last Resort
When default information is being passed along through a dynamic routing protocol, no further
configuration is required. The system periodically scans its routing table to choose the optimal default
network as its default route. In the case of RIP, there is only one choice, network 0.0.0.0. In the case of
IGRP, there might be several networks that can be candidates for the system default. The Cisco IOS
software uses both administrative distance and metric information to determine the default route
(gateway of last resort). The selected default route appears in the gateway of last resort display of the
show ip route EXEC command.
If dynamic default information is not being passed to the software, candidates for the default route are
specified with the ip default-network global configuration command. In this usage, the ip
default-network command takes an unconnected network as an argument. If this network appears in the
routing table from any source (dynamic or static), it is flagged as a candidate default route and is a
possible choice as the default route.
If the router has no interface on the default network, but does have a route to it, it considers this network
as a candidate default path. The route candidates are examined and the best one is chosen, based on
administrative distance and metric. The gateway to the best default path becomes the gateway of last
resort.
