Group,
If you have the following topology:
SW2
- -
- -
R3 ------ R1
And your running RIP on the segments between SW2-R3 and SW2-R1, and your
running some other IGP between R3 and R1. There are attached networks behind
R1 and R3, so your redistributing them into RIP on R1 and R3 with a metric of
1.
Now lets say you want to prefer R3 over R1 for a particular route, so you
apply an offset-list and corresponding access-list to the interface and route
you want to have a higher metric (SW2's fa0/14). I did this using the
following offset-list: offset-list 1 in 3 FastEthernet0/14. Clear ip route
*, and nothing changes.
However, when I apply an additional offset-list to the apposing interface
(fa0/15), offset-list 0 in 1 FastEthernet0/15, all of the desired metric now
take affect.
**note you must use SW2 to modify the metrics, using offsets on R1 and R3 is
prohibited.
My question is: When applying offset list inbound is there some rule that
states you must apply an offset-list to all interfaces in the protocol being
manipulated?
Or more plainly stated, why do I have to apply and offset to both interface
adjacent to R1 and R3 for offset-list to work?
Working config was:
router rip
version 2
passive-interface default
no passive-interface FastEthernet0/14
no passive-interface FastEthernet0/15
offset-list 1 in 3 FastEthernet0/14
offset-list 0 in 1 FastEthernet0/15
network 150.1.0.0
network 163.7.0.0
no auto-summary
!
ip classless
ip http server
!
!
access-list 1 permit 150.1.6.0
access-list 1 permit 150.1.2.0
access-list 1 permit 150.1.1.0
access-list 1 permit 163.7.6.0
access-list 1 permit 163.7.12.0
access-list 1 permit 204.12.7.0
Thanks,
