In the 7280R3/7500R3/7800R3 platform, EXP rewrite for IP-MPLS routed flows is derived from the DSCP of the packet. Using Qos Policy map , DSCP can be set as needed. But in this process, the egress IP TOS was also changed, which may cause issues later at customer edge.

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.

For MPLS forwarded traffic the tunnel destination needs to know the address-family of the payload IP/IPv6 packet to correctly parse the header. On some platforms this address-family is deduced from the address family of the Bottom of stack( BOS ) MPLS label seen by the router or by relying on the Ether Type in the Ethernet header.

MPLS-over-GRE encapsulation support in EOS 4.17.0 enables tunneling IPv4 packets over MPLS over GRE tunnels. This feature leverages next-hop group support in EOS. With this feature, IPv4 routes may be resolved via MPLS-over-GRE next-hop group to be able to push one MPLS label and then GRE encapsulate the resulting labelled IPv4 packet before sending out of the egress interface.

This feature extends the multi-domain EVPN VXLAN feature introduced to support interconnect with EVPN MPLS networks. The following diagram shows a multi-domain deployment with EVPN VXLAN in the data center and EVPN MPLS in the WAN. Note that this is the only supported deployment model, and that an EVPN MPLS network cannot peer with an EVPN MPLS network.
