Configuring Basic Eigrp Parameters - Cisco WS-CBS3032-DEL Software Configuration Manual

Chapter 39 Configuring IP Unicast Routing
To prevent an adjacency reset by the neighbors, the new stack master uses a new restart bit in the EIGRP
packet header. When the neighbor receives it, it synchronizes the stack in its peer list and maintains the
adjacency with the stack. The neighbor then sends its topology table to the stack master with the restart
bit set to show that it is NSF-aware and is aiding the new stack master.
If at least one of the stack peer neighbors is NSF-aware, the stack master receives updates and rebuilds
its database. Each NSF-aware neighbor sends an end-of-table (EOT) marker in the last update packet to
mark the end of the table content. The stack master recognizes the convergence when it receives the EOT
marker and begins sending updates. When the stack master has received all EOT markers from its
neighbors or when the NSF converge timer expires, EIGRP notifies the routing information database
(RIB) of convergence and floods its topology table to all NSF-aware peers.
Note NSF is not supported on interfaces configured for Hot Standby Router Protocol (HSRP).
Use the nsf EIGRP routing configuration command to enable EIGRP NSF routing. Use the show ip
protocols privileged EXEC command to verify that NSF is enabled. See the command reference for this
release for information about the nsf command.

Configuring Basic EIGRP Parameters

Beginning in privileged EXEC mode, follow these steps to configure EIGRP. Configuring the routing
process is required; other steps are optional:
Command
Step 1
configure terminal
Step 2 router eigrp autonomous-system
Step 3 nsf
Step 4 network network-number
Step 5 eigrp log-neighbor-changes
Step 6 metric weights tos k1 k2 k3 k4 k5
Step 7 offset list [access-list number | name] {in | out}
offset [type number]
Step 8 auto-summary

Purpose
Enter global configuration mode.
Enable an EIGRP routing process, and enter router configuration
mode. The autonomous-system number identifies the routes to
other EIGRP routers and tags routing information.
(Optional) Enable EIGRP NSF. Enter this command on the stack
master and on all of its peers.
Associate networks with an EIGRP routing process. EIGRP sends
updates to the interfaces in the specified networks.
(Optional) Enable logging of EIGRP neighbor changes to monitor
routing system stability.
(Optional) Adjust the EIGRP metric. Although the defaults have
been carefully set to provide excellent operation in most networks,
you can adjust them.
Caution Setting metrics is complex, and we do not recommend
doing without guidance from an experienced network
designer.
(Optional) Apply an offset list to routing metrics to increase
incoming and outgoing metrics to routes learned through EIGRP.
You can limit the offset list with an access list or an interface.
(Optional) Enable automatic summarization of subnet routes into
network-level routes.
