 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
