Hi,
i've an question. In an scenario like these:
-AS30>-R1---R3---R4---R6-<AS30--
R1 has an eBGP Peering to AS30
R1 has an iBGP Peering to R3 (ASxxx)
R3 is Routreflektor for the R1 and R6
R3 has an iBGP Peering to R6
R6 has an eBGP to AS30
R4 is an non BGP router.
R1 and R6 recive some Routes from AS30.
R3 and R1 next-hop-self for the internal AS
R3, R1 and R6 no sync because an rr is used.
Update source is allways loopback0.
In the routing table of R3 the routes from AS30 rechable via loopback R1 an
loopback R6. The networks are reachable from R6 and R1. But not from R6,
because the next hop isn't an directly connected network (the loopback).
1. Soulution is to redistribute the AS30 routes into igp at R1 and R6.
2. Soulution is to make gre tunnel and peer R1 to R3 and R6 to R3 via
gre-tunnel with source loopback and destination loopback and any network
over them.
Is ther an other soulution to solve the problem?
And what is the best solution for this problem or there any other solutions.
Regards
J.B.
