BGP route not advertised

Answered Question
Aug 19th, 2008

Good day...I have a quick question here I'm trying to advertised a subnet but when I do a show ip bgp I notice it says not advertised to any peer:

sh ip bgp

BGP routing table entry for, version 121282

Paths: (1 available, best #1, table Default-IP-Routing-Table, Advertisements suppressed by an aggregate.)

Not advertised to any peer

Local from (

Origin incomplete, metric 20, localpref 100, weight 32768, valid, sourced, best

what I'm actually trying to get to is a address which by the way comes up with the same as above if I do a

show ip bgp

What am I missing here?

I have this problem too.

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

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

do you mean aggregate summary?

aggregate-address summary-only

Harold Ritter Tue, 08/19/2008 - 07:28

Yes, that is what I meant. will be advertised if you take the aggregate command out of the configuration.

as mentioned previously simply take out the take the aggregate command will be advertised if you Take cxare Warren say hi to Carl for me

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

BGP routing table entry for, version 0

Paths: (1 available, no best path)

Not advertised to any peer

64643 7381 64940 64821, (aggregated by 64821, (received-only) from (

Origin IGP, localpref 100, valid, external, atomic-aggregate

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".

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
