- What is MPLS?
- MPLS (Multiprotocol Label Switching) is a routing technique used in telecommunications networks. It employs labels to direct data between network nodes efficiently.
- An MPLS header typically follows an Ethernet header and consists of one or more Label Stack Entries (LSE).
- Label Stack Entry (LSE) Format:
- Each LSE in the MPLS header is encoded as follows:
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 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+...
- Each LSE in the MPLS header is encoded as follows:
