Tag :: Virtual IP

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.

The ip address virtual command is generally used to conserve IP addresses in VXLAN deployments and can be used to provide an Anycast gateway. On a VLAN, the same IP address can be configured using this command on multiple VTEPS or on both MLAG devices. Release 4.22.1F introduced [ip address virtual support for PIM and IGMP]. Using that solution, users are required to configure pim ipv4 local-interface on the VLAN interface. PIM and IGMP then borrow the IP address from the local interface specified. Using this configuration, IGMP skips subnet checks for received control messages.

In certain VXLAN deployments with either NSX/Logical Router or EVPN IRB, active nodes hosting a virtual IP address
