Hi,
I am using OSPF as routing protocol between PE-PE. Can BGP be used
as routing protocol instead of OSPF? Also shall I have to use MP-BGP
here?
Consider the following scenario:
AC PW AC
CE1-------PE1==========PE2------CE2
Suppose I want to advertise a route from PE1 to PE2 where prefix would
be address of CE1. Can BGP be used here?
Thanks
Arnab
