How do we ensure symmetrical routing between a remote-site PC accessing non-critical traffic (email) over carrier 1 and critical traffic (ERP-Application) over carrier 2 to HQ?
We are migrating from a dual-carrier hub-n-spoke Frame network (OSPF-CEF destination based session) to a dual-carrier MPLS network (OSPF-BGP)where we want to influence critical traffic over carrier one and non-critical traffic over the other while maintaining symmetrical routing.
Are your servers in the same IP subnet? If they are, without NAT-ing, the only way I can think of is using policy-based routing.
If they are on different subnets, then another question I have is: what routing protocol do you run between your CPE (CE router) to your provider's MPLS edge (PE router)? If it's BGP, it's potentially quite straightforward: use AS_PATH prepending. Obviously you'd have to work with your MPLS providers to ensure your BGP metric will reflect on to the MPLS network as well.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
