[c-nsp] MTU Mismatch

[Jason LeBlanc]

From a routing perspective this makes sense.  Will there be any adverse effects if the Jumbo frames is bumped up anywhere in the chain?  Meaning L2 vs. the L3 Routing.  I believe thats where the MTU path discovery comes into play correct?  Sorry to add to this but while we were on the subject I figured I would ask :)  We want to use jumbo frames in a few environments but not at the cost of anything in the path.

Cheers,

// LeBlanc
