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.
