I work for a fixed wireless provider, and our mpls-capable backhauls are all running mpls with 9200 MTU with no problem. The only weirdness I encounter is if I have multiple equal-cost routes to the same location, one over MPLS and one not, end up having ping/unreachable issues from my monitoring equipment. The solution has been to cost one path (the MPLS) lower than the other. The only other problem I had was with radio's that didn't support larger 9000+ byte MTU packets - we've phased that radio out for now. if you run MPLS with 1500 byte MTU, you'll have issues with 1500 byte packets with the DF-bit set. That was a nasty discovery in the production network, your mileage will not vary with that problem. eric at techintegrity dot com 619-335-8148 voice & text www.techintegrity.com ericlouie on Twitter On Thu, Feb 5, 2015 at 1:55 PM, Scott Weeks <surfer@mauigateway.com> wrote:
Anyone doing MPLS over microwave radios? Please share your experiences on list or off.
