Hi Igor,
Try to use the OSPF Router-IDs instead of physical IPs:
distance 171 <<Router-ID>> 0.0.0.0 ACL
distance 171 <<Router-ID>> 0.0.0.0 ACL
This should work.
Regards
Marijo

Betreff: Re: distance for neighbor under eigrp
Since i could not make this work under eigrp, I turned to ospf for the same
command functionality. Ospf does allow for changing ad of selective external
routes, however the 'source ip' puzzles me even more - the only source that
works for me is the '0.0.0.0 255.255.255.255'.
Here is my simple setup :
R3-R2-R5-R3
R3 pulls the '178xxx' routes from external bb.
R3 and R2 run both eigrp and ospf, R5 runs ospf only. R2 and R3 do 2-way
redistribution. R5 s0/0 is 100.1.1.5, and R5 RID: 100.100.5.5
I need to make R2 take these routes from eigrp:
O E2 178.2.1.0 [110/20] via 100.1.1.5, 00:04:52, Serial1/0.1
O E2 178.2.3.0 [110/20] via 100.1.1.5, 00:04:52, Serial1/0.1
O E2 178.2.5.0 [110/20] via 100.1.1.5, 00:04:52, Serial1/0.1
Distance under eigrp did not work, so under ospf the two distance commands do
not make the change:
distance 171 100.1.1.5 0.0.0.0 ACL
distance 171 100.100.5.5 0.0.0.0 ACL
The only one that works is the 'distance 171 0.0.0.0 255.255.255.255 ACL',
which now makes my eigrp preferrable
R2#sh ip route | i 178
178.2.0.0/24 is subnetted, 3 subnets
D EX 178.2.1.0 [170/2323456] via 100.1.1.34, 00:00:09, Serial1/0.2
D EX 178.2.3.0 [170/2323456] via 100.1.1.34, 00:00:09, Serial1/0.2
D EX 178.2.5.0 [170/2323456] via 100.1.1.34, 00:00:09, Serial1/0.2
Anyone has any comments on why the ospf distance does not like the specific
source?
