Even I was just doing the same thing. The BGP routes are not installed in the r
outing table
if the IBGP peer does not match with BGP id and OSPF id.
I know that it should match but could someone explain me why and how it works.
R3#sh ip bgp 172.16.0.0
BGP routing table entry for 172.16.0.0/16, version 0
Paths: (1 available, no best path)
Not advertised to any peer
50
129.100.2.2 (metric 1563) from 129.100.2.2 (1.1.1.1)
Origin IGP, metric 0, localpref 100, valid, internal, not synchronized
Community: no-export
R3#
This route is advertised by the IBGP peer whose BGP id is 129.100.2.2 and OSPF
id is 1.1.1.1.
Hence not installed locally.
TIA,
Sarangan

Subject: RE: synchronization
well i have this situation , however the route dont synch in the bgp table
assume i have AS 30 , on the border i have R5 and internally i have R3 .R3 sync
h is on .
when i redistribute bgp into ospf on R5 , they reach R3 and show up in the data
base of the ospf as coming from R5 ID , in the bgp also show up as coming from
R5 ID ..however i didnt synch .
i noticed that it synch for while ..but then it just go without synch forever .
also note that R5 and R3 are woking over FR cloud where R5 is spoke ,R3 is the
hub and another peer to R5 in diff AS is the another spoke ..is there anything
related to next hop ?
thanks
