BGP Route Reflector

Hello All,

 

I have a router running BGP in an SP network. It is neither a  route reflector nor a client.

Can I convert the router into a route reflector without deleting the entire BGP instance on the router and recreating it in ASR router?

 

Thanks in advance.

Re: BGP Route Reflector

Hello rsharma,

 

You need to define all your neighbors as "route-reflector-client" in your Route Reflector ASR.

The next step is to change the iBGP full mesh. All the other routers should have bgp adjacency only with the route reflector.

 

Best Regards,

Michalis
