Dear all,
Sorry if this question is a little bit simple. I am trying to change the
announced metric of my E0, Lo0 and Tok0, and found this. Here is the situation.
s1|-----------|
-----|igrp only |------E0

Lo0 tok0
interface Loopback0

ip address 172.168.80.1 255.255.255.0

Show interface as following:
R8#sh int e0
Ethernet0 is up, line protocol is up
Hardware is Am79c970, address is 00e0.1ebb.6332 (bia 00e0.1ebb.6332)
Internet address is 172.168.48.2/24
MTU 1500 bytes, BW 1000 Kbit, DLY 1000 usec,

R8#sh int lo0
Loopback0 is up, line protocol is up
Hardware is Loopback
Internet address is 160.10.10.1/24
MTU 1514 bytes, BW 8000000 Kbit, DLY 5000 usec,

With debug ip igrp, I got this on S1
3d19h: IGRP: sending update to 255.255.255.255 via Serial1 (172.168.200.8)
3d19h: subnet 172.168.48.0, metric=5100
3d19h: subnet 172.168.80.0, metric=5100
3d19h: network 160.10.0.0, metric=501
There are two questions here:
1. Supposed, with my redistribute-connected route-map, the assigned metric
should affects Lo0 interface only (as calculated, should be 5100). But it
is however affecting my tok0 and E0 too.
2. How come my annouced Lo0 metric becomes 501 (using BWmin:8,000,000 and
dly:5000 at the interface), but not as calculated 5100?
Am I overlooking something? Thanks.
