I have a CAT6509 with MPLS.. two redundant MSFC2 blades. Whenever I go in to configure one of the MSFC's I get the message:
%MROUTE-4-MTU_MISMATCH : WARNING: With IP multicast enabled, interfaces which transmit traffic from larger to smaller MTU interfaces may not be hardware switched due to fragmentation. A degradation in performance may occur.
According to Cisco:
Explanation This warning message provides information about transmitting traffic from larger to smaller MTU interfaces.
Recommended Action Set MTU values on all interfaces to be identical to avoid fragmentation.
I am not sure what to do about this because I do not see any specific MTU settings. Can someone help me with this?
