Description: The MPLS MTU(Maximum Transmission Unit) of an interface.
What is h3cMplsExtMtu?
This object sets the MPLS MTU, in bytes, for a specific interface, constrained to the range 46 to 65535. It determines the largest labeled packet size the interface will forward, which matters because MPLS labels add overhead that can push packets past the underlying link's Ethernet MTU. For example, an admin might raise this to 1508 to accommodate a single MPLS label pushed onto 1500-byte IP packets.
