Hello,
i have some problems with routing updates in my mpls could. i have three routers, one is configured as route reflector the other two are clients. I have three vrf's configured. The topology and config is attched.
on the router p1 i do net get any routing information from the other sites.
here the output from p2
show ip bgp vpnv4 rd 65000:100
BGP table version is 13, local router ID is 172.16.131.252

somehow the bgp session is established but vpnv4 doesn't get established.

on the p1 i get every couple minutes this

on p2 i get this

any idea why this happens?
The p2 and p1 are 2900 running 153-3.M.
thanks in advanced
