Good day...I have a quick question here I'm trying to advertised a 205.248.197.0 subnet but when I do a show ip bgp 205.248.197.0 I notice it says not advertised to any peer:
sh ip bgp 205.248.197.0
BGP routing table entry for 205.248.197.0/25, version 121282
Paths: (1 available, best #1, table Default-IP-Routing-Table, Advertisements suppressed by an aggregate.)
Not advertised to any peer
Local
172.19.205.5 from 0.0.0.0 (172.19.103.45)
Origin incomplete, metric 20, localpref 100, weight 32768, valid, sourced, best
what I'm actually trying to get to is a 205.248.197.152 address which by the way comes up with the same as above if I do a
show ip bgp 205.248.197.152
What am I missing here?

Can you do a "show ip bgp 205.248.197.0 255.255.255.128" on the receiving router.

Warren,
This prefix is suppressed due to an "aggregate no-summary" command being configured for an aggregate route covering this prefix.

so if I take this Aggregate out then it should be good?
08-19-2008 07:25 AM
do you mean aggregate summary?
aggregate-address 205.248.197.0 255.255.255.0 summary-only
08-19-2008 07:28 AM
Yes, that is what I meant. 205.248.197.0/25 will be advertised if you take the aggregate command out of the configuration.

one more question I took out the aggregate as suggested and now I do see it being adversited
I go to the distant and see this now:
sh ip bgp 205.248.197.152
BGP routing table entry for 205.248.197.0/24, version 0
Paths: (1 available, no best path)
Not advertised to any peer
64643 7381 64940 64821, (aggregated by 64821 172.19.103.45), (received-only)
168.162.52.185 from 168.162.52.185 (10.128.191.82)
Origin IGP, localpref 100, valid, external, atomic-aggregate

Warren,
The received-only status means that the prefix is being filtered by an inbound policy. Make sure your inbound policy allows that prefix.

Oops, I just figured that this is actually the aggregate. Can you do a "show ip bgp 205.248.197.0 255.255.255.128".

Please post the entire BGP config, including any route maps and filters.

Sorry guys for wasting your time, I didn't bother checking that I was receiving the proper routes in chicago. I checked to see and found out that even though I was advertising locally the BGP route in Chicago I wasn't accepting it. Once I did that all is good now. Sorry about that
