Variable-Length Subnet Mask
Definition
Variable-Length Subnet Mask(VLSM): provides the ability to have more than
one subnet mask within your major network. It also allows you to further
subnet your already subnetted networks. Requires Classless Routing
Protocols.

Advantages
Efficient Use of IP addresses: Without VLSMs, networks would have to use
the same subnet mask throughout the network. But all your networks don’t
have the same number of hosts.
For example: You have 2 LAN connected via a Serial Point-to-point connection.
Each LAN has 50 Hosts on it. When you assign the subnet mask, it has to be
consistent across your network. So you end up assign a sub-network address
to the WAN connection with 62 hosts, whereas you only need 2.
Greater Capability for Route Summarization: Route Summarization is
covered in detail, later on in this module.

this feature will eliminate the issue pertaining to discontiguous networks.  Bounded: Updates are sent to affected routers only. EIGRP will send a query to its neighbor/s to discover an alternate path. • Reduced Bandwidth Usage/Incremental Updates: In EIGRP updates are still sent to directly connected neighbors. • Advance Distance Vector/Hybrid routing protocol that has the behavior of distance vector with several Link State features. Another issue regarding bandwidth usage is the fact that EIGRP by default will only consume 50% of the bandwidth of the link during convergence. much like distance vector protocols. such as dynamic neighbor discovery.21. These queries are propagated until an alternate route is found. the reason EIGRP does not support clear text is because. Features • Rapid Convergence: EIGRP uses DUAL to achieve rapid convergence. If no backup route exists. • Security: With IOS version 11.netscopeme. EIGRP can authenticate using only MD5.3 or better. It stores a backup route if one is available. • First released in 1994 with IOS version 9. so it can quickly re-converge incase a route goes down. but these updates are:  Non-Periodic: The updates are not sent at regular intervals.  Partial: Updates will include the routes that are changed and not every route in the routing table. VLSM and Manual Summarization is also supported on any router within the enterprise. This parameter can be adjusted to a higher or lower value eith the following command: Ip bandwidth-percent eigrp <AS number> <number that represents the percentage> • Classless Routing Protocol: This means that advertised routes will include their subnet mask.com Page 33 of 197 .Enhanced IGRP (EIGRP) • Cisco proprietary routing protocol.com Khawarb@khawarb. rather when a metric or a topology change occurs.

For RTMP it supports event driven updates. NBMA topology such as Frame-Relay. EIGRP will also perform auto-redistribution with NLSP. CIDR/Supernetting. EIGRP supports incremental SAP and RIP updates.0. • Metrics: EIGRP uses 2 step metric: 1. Point to point topology such as HDLC. • 100% Loop Free: EIGRP uses DUAL to attain fast convergence while maintaining a totally loop free topology at every instance.netscopeme. and also a better metric calculation.0.  The vector metric of a route received from a neighbor is computed from the received vector metric and the metric of the interface through which the route was received. • Multiple Network Layer Protocol Support: EIGRP can support IP. and AppleTalk.10 instead of broadcast. But the routes are not encrypted. IPXRIP. • Use Of Multicast Instead Of Broadcast: EIGRP uses multicast address of 224. Copyrights Netscope FZ LLC 2007-2015 Website: http://www. and all Cisco routers support MD5 authentication. • OSI and EIGRP: Like all TCP/IP routing protocols EIGRP relies in IP to deliver the packets. and it uses bandwidth + delay which is far more better than just Ticks and Hops used by IPXRIP. VLSM. but it must run in a clientless networks(WAN). • Support of hierarchical addressing scheme: Eigrp supports FLSM.EIGRP can only be used within CISCO routers. EIGRP maps to the transport layer of OSI and uses protocol number 88. • Support Of Different Topology: EIGRP can support broadcast multiaccess topologies such as Token-Ring. • Easy configuration: The configuration of EIGRP is very similar to IGRP which is very simple. By default EIGRP will use up to 4 paths and this can be increased to 6. RTMP. MAX Load. VECTOR 2. so a sniffer can easily see the password/s. COMPOSITE  Vector metric is: Min MTU.

that the route must be advertised by a downstream neighbor (with respect to the destination). in this state the router sends out queries to all neighbors in order to find a route to that destination.

EIGRP Summarization

Purpose: Smaller routing table, smaller updates, and query boundary.
Auto-summarization: Auto-summarization is turned on by default, and
it is done on the major network boundary, subnets are summarized to a
single classfull networks.
Manual Summarization: Auto-summarization can be turned off, unlike
OSPF manual summarization can be done on any router in any location.

NBMA Networks



Networks like Frame Relay,X.25 or ATM, are examples of NBMA
networks.
These type of networks do have the capability to connect more than two
routers but have no capability of broadcasts. A packet sent by one of the
attached routers would not be received by all other attached routers.
OSPF routers on NBMA elect a DR and BDR and all OSPF packets are
unicast.
All routers form an adjacency with the DR and BDR.
Careful selection of DR and BDR has to be done in the Hub-and-Spoke
configuration of NBMA networks.

OSPF Protocols and Packets

OSPF consists of a set of individual protocols all working together to
build a fast and scalable interior routing protocol.
OSPF protocols are:
• Hello Protocol
• Exchange Protocol
• Flooding Protocol
These protocols are used in different packet types. The different packet
types, their descriptions are listed in the following Table.

Problems with a large OSPF single
area

Frequent SPF algorithm calculation: In large networks, network changes
are inevitable, so the routers would have to spend more CPU cycles for
recalculating SPF.

Large Routing Table: Each router would need to maintain at least one
entry per network, and if we have provided redundancy to some of the
links, then more entries will be found in the routing table.

Huge Link-State Database: Remember each point-to-point link will have
2 entries and so on, so one can imagine the number of entries in that
database.

Solution in Hierarchical routing (multiple Areas)

In OSPF we can divide a large Area into smaller areas.

Routing still occurs between the areas called inter-area routing.

If one of the areas is having a flapping link, it will not have an effect on
the other areas, because the traffic will always be restricted to that area
If you summarization is performed on the ABR.

Benefits

Reduced Frequency of SPF calculation: detailed routing information is
kept within each area so its not necessary to flood all Link-State changes
to all other areas, thus not all routers need to run the SPF calculations.

Smaller Routing Table: Because detailed routing information is kept
within an area, the routers within an area will have smaller routing table.

Reduced Link-State Updates: LSU s can contain a variety of LSA types,
instead of sending an LSU about each network within an area, you can
advertise a single or fewer summarized routes between areas to reduce
overhead associated with LSU s.
