I think we have come across this issue before. Anyway, it's because the IGP rou
te 200.100.100.0/24 is from R2. But the iBGP route is from R3. When you have OS
PF as IGP and want to syn with BGP, the route originator R-Ids have to be the s
ame. Otherwaise it's not synchronized and, hence, not advertise to R5.

Hi group,
I just run into another interesting little problem.
I have R1-R2---R3
| |
\ /
R4---R5
R1 is running RiP. R2,R3,R4,R5 are running ospf. R2 is
redistributing rip into ospf domain.R1 is inserting
route 200.100.100.0/24 to BGP through network
statement and Redistributing this route into Rip as
well. R1 is in AS1 , R2 in AS3, and R5,R4,R5 in As
3.EBGP sessions R1-R2, R2-R3. IBGP sesions R3-R4,
R4-R5. R4 is route reflector.Synch is enable on all
the routers.Question is why on R4 BGP table says, that
route 200.100.100.0/24 is not synchronized even it's
known through ospf and is not being pushed to R5.
All routers have hard coded identical routers id in
ospf and BGP.
I've been struggling almost a week with this one.I
searched and read white papers on CCO - I still don't
understand.I'm missing really something important.
Can you help?
Paul
