EVPN VXLAN single-gateway centralized routing

Description In a traditional EVPN VXLAN centralized anycast gateway deployment, multiple L3 VTEPs serve the role of the centralized anycast gateway.  In order for hosts to have a consistent ARP binding for any of the individual centralized gateway VTEPs, each VTEP operating as a centralized gateway is configured with a virtual router MAC (VARP MAC), and a virtual VTEP IP (VARP VTEP IP), that is shared between all of the L3 VTEPs operating as centralized gateways.  Each centralized gateway VTEP also advertises an EVPN type-3 route for both its primary VTEP IP and VARP VTEP IP, so both IPs end...

EVPN E-Tree for MPLS

Description E-Tree is an L2 EVPN service (defined in RFC8317) in which each attachment circuit (AC) is assigned a role of Root or Leaf.  Once roles are assigned, forwarding rules are enforced such that: Root ACs can communicate with leaf ACs and other root ACs Leaf ACs can only communicate with root ACs.  Leaf AC to leaf AC traffic is blocked In this implementation, ACs are configured at the VLAN level, and the forwarding rules are enforced using a combination of local configuration of leaf VLANs (for local hosts), and  asymmetric route targets (for remote hosts).

VLAN-aware bundle Addition/Removal of VLANs from VLAN set

Description In EVPN, when configuring the member VLANs for a VLAN-aware bundle, the existing configuration command only allows the specification of a VLAN range string, which replaces the previously configured VLAN range string.  This enhancement adds new syntax to add or remove additional VLANs from the currently configured VLAN-aware bundle VLAN list. Platform Compatibility Platform independent Configuration The existing configuration CLI for configuring the member VLANs in a VLAN-aware bundle is: vlan <range>   This takes a VLAN range-string and uses it to replace the currently configured VLAN range-string.  The updated CLI syntax is now: vlan [ add | remove...
