Dear Salman
the main idea of the offset list, is to change the FD for one of the link so
that it will becomes equal to the the FD of the other link.
Ex.
Use an offset-list on R4 to Modify the Composite Metric at R2
The Composite Metric on R2 can be modified using an offset-list on router
R4. An offset-list value of 20 on R4 increases the Composite Metric for the
path R2-R4 by 20 on R2. Therefore, the path R2-R4 becomes a backup path to
R2-R3. An offset-list is the preferred method if:
-
You only want to influence a particular path being advertised.
-
Additional routers are connected to the 10.1.3.0/24 subnet and you do
not want to influence paths originated by the routers.
1.
Configure an offset-list on R4 that increases (by 20) the delay for
any route starting with *10.1.3.x*.
R4# *configure terminal*
Enter configuration commands, one per line. End with CNTL/Z.
R4(config)# *access-list 99 permit 10.1.3.0 0.0.0.255*
R4(config)# *router eigrp 1*
R4(config-router)# *offset-list 99 out 20 e0/0*
R4(config-router)# *end*
