Hi,
2.4. MTU TLV The MTU TLV encodes information on the maximum transmission unit for an LSP, from the advertising LSR to the egress(es) over all valid paths. The encoding for the MTU TLV is: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |1|1| MTU TLV (0x0XXX) | Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | MTU | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ MTU This is a 16-bit unsigned integer that represents the MTU in octets for an LSP or segment of an LSP. Is this unnecessarily limiting? Shouldn't we
support MPLS over L2 technologies that support larger than 64k
MTUs?
