This is the remark i have,
1. The segments are annouce throught bgp season
2. advertise using prefix to the client
3.bgp summ up side 1w6d
4 neighbor adver shows all routes
Thanks

Hi,
without further config snippet, topology and also what is happening on client peer we can't do much.

I'm assuming these routes do not show up on 10.10.10.9?
neighbor 10.10.10.9 route-map Inbound_MNC_la_Peering in
neighbor 10.10.10.9 route-map Outbound_MNC_la_Peering out
What do these route-maps do?
12-06-2011 02:46 AM
they do show up when u do sh ip bgp neig 10.10.10.9 adv
The route maps are used to filter out/in received and advertised routes using ip prefix-list
Thanks

Could there be anything blocking them on the client side?
Or do you even have access to that?
12-06-2011 03:00 AM
I cant really tell,give that i do not have access to the client side and can't know about if there is access-list or not
