EVPN E-LAN over SRv6

EVPN E-LAN is a framework for delivering multipoint-to-multipoint VPN service with the EVPN signaling mechanisms. E-LAN service allows service providers to offer services that manage the L2 learning very efficiently. Starting in Junos OS Release 23.4R1, you can configure single-active or all-active multi-homed EVPN-ELAN service using segment routing over IPv6 (SRv6). To provide SRv6 service, the egress PE signals an SRv6 Service SID with the VPN route. The ingress PE encapsulates the Service SID in the VPN packet in an outer IPv6 header where the destination address is the SRv6 SID advertised by the egress PE and is routable in the underlay. The nodes between the PEs only need to support plain IPv6 forwarding. We support SRv6 micro-SID & Segment Routing Header (SRH) based control planes and forwarding. Different endpoint behaviors are defined for SRv6 services on the egress node.
