Hi, just to get a second opinion on this exercise:
"task:Configure BGP AS 1 between R2, R3, R4, and R6. Do not use a full mesh. "
So does it mean I should use Route-Reflectors (or even confederation) to accomplish this, right?
More than probably , yes.
Funny because if you are using a Route Reflector, I thought that still provides the 'full-mesh'
sessions, technically speaking.
full mesh here means every router has a bgp peering with all other routers which is not the case with a route-reflector.
I agree with alain as the no. of ibgp sessions required between four routers will be 6 (n(n-1)/2).
And if you introduce one RR in between them the no. of sessions will be 4 because ibgp full mesh rule will be relaxed here.
Hope this helps
