VRRP (Virtual Router Redundancy Protocol) is an IETF standard protocol to create a redundant virtual gateway. It allows routers to create a virtual default gateway IP address where they share the same IP address. When the primary router fails, the backup router automatically takes over. The Virtual Router Redundancy Protocol (VRRP) is an election protocol that. For details about the mapping between software versions and switch models, see the Hardware Center. Access switches are dual-homed to core devices on a data center network. On the Catalyst, Interface VLAN 1622 is configured with multiple IP addresses on a single SVI, as shown below: For the migration to the Nexus N9K, can I configure multiple VRRP virtual IP. Have both CORE switches have a route via each link to the firewall and control the preferred path with OSPF cost. Also add a trunk group ether-channel between the core switches too.
