EVPN MPLS VPWS (RFC 8214) provides the ability to forward customer traffic to / from a given attachment circuit (AC) without any MAC lookup / learning. The basic advantage of VPWS over an L2 EVPN is the reduced control plane signalling due to not exchanging MAC address information. In contrast to LDP pseudowires, EVPN MPLS VPWS uses BGP for signalling. Port based and VLAN based services are supported.

Flexible cross-connect service is an extension of EVPN MPLS Virtual Private Wire Service (VPWS) (RFC 8214). It allows for multiplexing multiple attachment circuits across different Ethernet Segments and physical interfaces into a single EVPN VPWS service tunnel while still providing single-active and all-active multi-homing.

A forwarding equivalence class (FEC) entry is the data structure that holds all reachable vias where the packets should be sent to, for certain routes. Before this feature, a FEC could not contain both IPv4 next hop vias and IPv6 next hop vias. This feature starts supporting FECs that have both IPv4 next hop vias and IPv6 next hop vias. In an Equal Cost Multi-Path (ECMP) FEC, some of the vias may have IPv4 next hop and others may have IPv6 next hop.

Prior to release EOS 4.29.1, a statically configured BGP neighbor, listen range or interface peer could reference a single peer group for inheriting configuration parameters. EOS 4.29.1 adds the ability for that peer group to inherit configuration from up to 8 additional “ancestor” peer groups. The term “leaf peer group” is given to the peer group which is directly referenced by the BGP neighbor, listen range or interface peer.

This feature enables the user to configure a list or range of BGP attributes to be ignored by the router on receipt of a BGP update message. The BGP attributes are discarded from the BGP update message, and unless the action of discarding an attribute causes the update message to trigger error handling, then the update message is parsed as normal.
