Traffic path of enterprise public prefix for a remote office with Internet and MPLS connection.

Hello all,

I have a question regarding how a remote site should route traffic to the enterprise's public prefixes when it has a local Internet and MPLS connection. The two options are two have all traffic to public prefixes route over the Internet connection. The other option is to have the headend MPLS router advertise the enterprise's public prefixes over the MPLS cloud, which would then cause the remote sites to route traffic to the enterprise's public prefixes through the MPLS connection.

My assumtion is to have all Internet traffic traverse the Internet even if it belongs to the enterprise. What is the preferred method? Please let me know if this wasn't clear.

You are right. Main issue is to maintain symmetric traffic paths.

This is at least a requirement for your internet traffic because it has to transit stateful firewalls, IPS devices and similar. Any asymmetry there will kill you or at least provide ample source for tricky issues.
