Virtual Router Redundancy Protocol (VRRP) provides high availability for the default gateway within a broadcast domain. Previously, in VRRP-based deployments with DHCP Relay, each participating router forwarded DHCP requests using its interface IP address, which resulted in duplicate relay requests, duplicate DHCP server ACKs, and increased control-plane noise. This feature solves these issues by making DHCP relay processing VRRP state-aware.
