MPLS encapsulation
In MPLS-based EVPN, Ethernet frames are encapsulated with: • MPLS label stack: Each EVPN instance is associated with a unique label that helps in identifying the destination bridge domain. • Control word (optional): Provides additional information for synchronization and alignment in certain scenarios. The encapsulated packet flow includes: • Original Ethernet frame • MPLS labels • Outer IP header (in case of IP/MPLS networks) EVPNs are covered by a number of Internet RFCs, including: • • • • • == See also ==
