I need to know the best practice for the following scenario.
I am Service Provider... and i have a Customer with lets say with 10 branches (which communicates with each other) and are terminating on 10 different Nodes (PE) in my core network.
1) Should i give different AS Number (private as numbers) to each branch ??
2) Should i give same AS number (private as numbers) to each branch and use as-override??
which approach is better, secure and less prone to mistakes.???
i have similar setup for customers both on MPLS (L3VPN) and IP only.
