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.

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.
