Description: The MPLS MTU(Maximum Transmission Unit) of an interface.
What is hh3cMplsExtMtu?
This value (46-65535) sets the MPLS MTU for an interface, the maximum size of a labeled packet the interface will send or accept. An admin tunes it to avoid fragmentation issues once label stacking adds overhead beyond the interface's normal IP MTU. For example, an admin might raise this value on a core link carrying multiple stacked MPLS labels to accommodate the extra header bytes.
