Hello
I have a question for someone with a grasp on BGP Confederations and how
synchronization affects it. My scenario
AS301/R7 --- AS501/sub-AS65001/R3 --- AS501/sub-AS65002/R1 --- AS101/R9
|
|
AS501/subAS65001/R2
Routers R1, R2 and R3 are in a single OSPF domain. The BGP router-id's and
OSPF router-ids are the same on all routers.
My problem --- an advertisement comes in from AS101/R9, let say 49.0.0.0/8.
That advertisement is propagated via OSPF to router R2 with R1's OSPF
router-id.
When that advertisement crosses the sub-AS border between R1 and R3, the BGP
router-id is changed to that of R3, therefor when the iBGP route gets to R2,
the BGP router-id is from R3 while the OSPF router-id is from R1. The result
is no sync. Any advice????
