Tag :: ip Address Virtual

This feature adds the ability for an L3 default gateway TEP in a Centralized Gateway topology to advertise its SVI virtual IP addresses to VARP MAC bindings and primary addresses to System MAC bindings using EVPN type-2 routes for EVPN VXLAN overlays. Two new commands, redistribute router-mac virtual-ip[next-hop vtep primary] and redistribute router-mac system ip are introduced to enable the redistributions. This would help the L2 TEP on the network to learn the default gateway IP without flooding an ARP request for the gateway IP. This feature is only intended for Centralized Gateway Topologies.

VXLAN ARP and IPv6 Neighbor Discovery (NDP) packet headend replication capability via VxlanSwFwd matches the COPP rate limit for these packets for the supported platforms regardless of the size of the VXLAN flood VTEP list. However, there still remains a case where the handling capacity is limited by CPU: the handling of ARP broadcast and NS multicast that result from Glean traffic (post routing).
