Hi,
I have got a problem with OSPF-BGP-Synch. topology looks like :
R1---R2(RR)---R3 all are in AS1, R2 is RR. all nei on loopback IPs,
10.1.1.1, 10.2.2.2, 10.3.3.3
BGP router id and OSPF router id are same at the routers. Synch is on.
after i advertise one block from R1, I can see it on the BGP table of
R3.
But when I look the route it is not schronized. Any ideas ?
