We have two or more mpls line at each branch with different isps and each line will be terminated on one Cisco router.. We r going to use bgp for routing. Do we require publice ASN or we can use private As number? Please share your answers thanks
If we are talking about connectivity in between two branch i think there is no need to use bgp protocol because you can achieve the same results by just using static route into each router. but if you have to use bgp you can use private ASN.
