Hi..
Some questions on synchronisation. Below is the setup
[r6]
/ \
[r1]/ \[r2]
|
|
[r3]
r1,r6,r2 in AS 100; r1 and r2 running IBGP
r3 in AS 200
r3 announced the network 10.10.10.0 to r1 via EBGP.
r2 then rx 10.10.10.0 in its BGP table via IBGP from r1.
r2 did not put the route 10.10.10.0 into its IP routing
table becos it does not know how to reach 10.10.10.0.
This is a synchronisation issue.
So I put a static route
ip route 10.10.10.0 255.255.255.0 next-hop-to-r6
with this statement, there is a static entry in the routing
table. But debug ip bgp update shows that it is not synchronised.
BGP: nettable_walker 10.10.10.0/255.255.255.0 calling revise_route
BGP: revise route installing 10.10.10.0/255.255.255.0 -> 128.213.63.2
BGP: nettable_walker 10.10.10.0/255.255.255.0 not synchronized
WHY ?? I thot syncrhonisation rule states that if IGP knows the route
it'll be considered synchronised and the router will advertise
the route to external peers.
Any advice ??
Thanks
Eng Wee
