Very easy question on BGP full-mesh

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?

Hi,

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.

Hello,

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

Regards

Mahesh
