Hi, All!
I have installed route-server for small exchange point.
Router is Cisco 2801, IOS c2801-ipbasek9-mz.124-24.T2.bin.
All peers connected to the same subnet on FastEthernet0/0.

All neighbors configured as a peer-group members, except firs
which is an iBGP peer in the same AS.
So, we have three update-groups:
BGP version 4 update-group 1, internal, Address Family: IPv4 Unicast
BGP Update version : 294/0, messages 0
4 octets ASN capable
Community attribute sent to this neighbor
Route map for outgoing advertisements is BGP-IX-OUT
Update messages formatted 150, replicated 0
Number of NLRIs in the update sent: max 22, min 0
Minimum time between advertisement runs is 0 seconds
Has 1 member (* indicates the members currently being sent updates):
XXX.YYY.ZZZ.130
BGP version 4 update-group 2, external, Address Family: IPv4 Unicast
BGP Update version : 294/0, messages 0
Private AS number removed from updates to this neighbor
Community attribute sent to this neighbor
Route map for outgoing advertisements is BGP-IX-OUT
Update messages formatted 386, replicated 181
Number of NLRIs in the update sent: max 44, min 0
Minimum time between advertisement runs is 30 seconds
Has 5 members (* indicates the members currently being sent updates):
XXX.YYY.ZZZ.132 XXX.YYY.ZZZ.133 XXX.YYY.ZZZ.134 XXX.YYY.ZZZ.135
XXX.YYY.ZZZ.139
BGP version 4 update-group 3, external, Address Family: IPv4 Unicast
BGP Update version : 294/0, messages 0
4 octets ASN capable
Private AS number removed from updates to this neighbor
Community attribute sent to this neighbor
Route map for outgoing advertisements is BGP-IX-OUT
Update messages formatted 165, replicated 313
Number of NLRIs in the update sent: max 44, min 0
Minimum time between advertisement runs is 30 seconds
Has 4 members (* indicates the members currently being sent updates):
XXX.YYY.ZZZ.131 XXX.YYY.ZZZ.136 XXX.YYY.ZZZ.137 XXX.YYY.ZZZ.138
At the present all works as expected. But only thing which confuse me
is the output of 'sh ip bgp neigbor x.x.x.x adv' command.
For any neigbors from update-group 3 it shows all routes, but for
neighbors from update-group 2 only some subset -some portion of last
received updates. Also values for replicated updates also different.
But on the other end router sees all prefixes.
Can someone explain me this situation, or at least point me in right
direction, please? May be it's a bug in IOS and I need to upgrade to
advipservices?
Thanks in advance!
And Merry Christmas and Happy New Year! :)
