16.4 Configuring Metric Parameters
A RIP offset list allows you to add to the metric of specific inbound or outbound routes
learned or advertised by RIP. RIP offset lists provide a simple method for adding to the
cost of specific routes and therefore biasing the router’s route selection away from those
routes. An offset list consists of the following parameters:
An ACL that specifies the routes to which to add the metric.
The direction:
In: applies to routes the router learns from RIP neighbors.
Out: applies to routes the router is advertising to its RIP neighbors.
The offset value that will be added to the routing metric of the routes that match
the ACL.
The interface that the offset list applies (optional).
If a route matches both a global offset list (without specified interface) and an
interface-based offset list, the interface-based offset list takes precedence. The
interface-based offset list’s metric is added to the route in this case.
This example R2 will advertise route 10.10.11.0/24 out of interface eth-0-2 with metric
added 2.

R2
DUT# configure terminal Enter the Configure mode.
DUT(config)#ip access-list ripoffset Create IP access list named ripoffset.
DUT(config-ip-acl)#permit any
10.10.11.0 0.0.0.255 any
Configure the access list to match route 10.10.11.0/24.
DUT(config-ip-acl)# router rip Enter the RIP routing process.
DUT(config-router)# offset-list ripoffset
out 2 eth-0-2
RIP updates being sent out from interface eth-0-2 will adds 2 hops to
the routes matching the access list ripoffset.
Validation Commands
