Hi,
I am using 6 routers in gns3 and there is a problem in route advertisements.
R2 is in AS 200, R3,R4,R5 are in AS 100 and R6 is in AS 300,
R2-> R3 eBGP
R3,R4,R5 are in same AS, iBPG(using Route reflector instead of fullmesh iBGP)
R5-> R6 eBGP.
R3 to R4 i have used next-hop-self and same with R5 to R4.
Syn is off.
Now the problem is R4 is not advertising eBGP routes to either side, so there is no reachability from R2 to R6.
Please help me with this, Where i have gone wrong, and what changes can i make to make this work.
Below are the configs and topology i have used.
config for R6 (cannot attach more than 5 files, so m adding config of R6 here)
