Chapter 10 Configuring Networking Protocols
Configuring IP Routing
To configure RIP, enable RIP routing for a network and optionally configure other parameters.
Beginning in privileged EXEC mode, follow these steps to enable and configure RIP:
Neighbor None defined.
Network None specified.
Offset list Disabled.
Output delay 0 milliseconds.
Timers basic Update: 30 seconds.
Invalid: 180 seconds.
Hold-down: 180 seconds.
Flush: 240 seconds.
Validate-update-source Enabled.
Version Receives RIP Version 1 and Version 2 packets;
sends Version 1 packets.

Feature Default Setting
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# ip routing
Enables IP routing. (Required only if IP routing is disabled.)
Step 3
Router(config)# router rip
Enables a RIP routing process, and enters router configuration mode.
Step 4
Router(config-router)# network
network number
Associates a network with a RIP routing process. You can specify
multiple network commands. RIP routing updates are sent and received
through interfaces only on these networks.
Step 5
Router(config-router)# neighbor
ip-address
(Optional) Defines a neighboring router with which to exchange routing
information. This step allows routing updates from RIP (normally a
broadcast protocol) to reach nonbroadcast networks.
Step 6
Router(config-router)# offset list
[
access-list number
|
name
] {in |
out}
offset
[
type number
]
(Optional) Applies an offset list to routing metrics to increase incoming
and outgoing metrics to routes learned through RIP. You can limit the
offset list with an access list or an interface.
Step 7
Router(config-router)# timers basic
update invalid holddown flush
(Optional) Adjusts routing protocol timers. Valid ranges for all timers are
0 to 4294967295 seconds.
• update—The time (in seconds) between sending of routing updates.
The default is 30 seconds.
• invalid—The timer interval (in seconds) after which a route is
declared invalid. The default is 180 seconds.
• holddown—The time (in seconds) that must pass before a route is
removed from the routing table. The default is 180 seconds.
• flush—The amount of time (in seconds) for which routing updates
are postponed. The default is 240 seconds.
