Question : Full meshed iBGP connection formula ?

Someone tell me how many connection do I need to make for iBGP full mesh with 15 routers(total) ?

Answer :

The formula is N(N-1)/2, N=node=Routers.
So, 15(15-1)/2 = (15x14)/2 = 210.
Wow, do you have 15 routers ?

If you are planning to apply iBGP on your network, there are many solution to avoid full meshed network.

Thank you
