Hi GS!
This is topology: R1------R2----R3----R4-----R5
IGP information:
R2,R3,R4: running OSPF
BGP information:
R1 in AS 1000
R5 in AS 5000
R2,R3,R4 in AS 100, must enable synchronyzation all router and R3 is
route-reflector of R2, R4
The problem is: R1 advertise network "X" to R2 via BGP, then R2 redistribute
network "X" to OSPF because of BGP synchronyzation rule, and at R4 received
2 route "X": one via OSPF(with router-id R2) and one via BGP(with router-id
R3). Because of this, route "X" unsyn. So R4 DO NOT advertise route "X" to
R5!
I can not find solution to this situation! Can not change bgp router-id on
R3 equal with ospf router-id on R2 (if we do that, route "X" via BGP on R3
will unsyn).
Could anyone help me with this?
Thanks!
