I have R4 as an internal router to Area 1.
R2 and R5 are border routers generating a type-3 LSA for route 1.1.1.1
into area 1.
Instead of using cost, I would like to use distance (if possible) to
alter path selection.
R4 has two routes to 1.1.1.1:
R4#sho ip route | sec 1.1.1.1
O IA 1.1.1.1 [110/4] via 192.168.45.5, 00:01:10, Serial1/0
[110/4] via 192.168.34.3, 00:01:10, Serial1/1
R4#
Here we see both type-3 LSAs, one each generated by R2 and R5:
R4#sho ip osp database
Summary Net Link States (Area 1)
Link ID ADV Router Age Seq# Checksum
1.1.1.1 2.2.2.2 207 0x80000001 0x0033FB
1.1.1.1 5.5.5.5 170 0x80000002 0x00E040
R4(config)#router ospf 1
R4(config-router)#distance 100 5.5.5.5 0.0.0.0
Both routes get changed:
R4#sho ip route | sec 1.1.1.1
O IA 1.1.1.1 [100/4] via 192.168.45.5, 00:00:03, Serial1/0
[100/4] via 192.168.34.3, 00:00:03, Serial1/1
Why does the command alter both routes AD if I specified wildcard mask
of 0.0.0.0 ?
I know that the ACL portion of the command works, to alter distance of
specific routes, but it appears the router-id/mask has no impact in
choosing between different ABR's.
