VRRP Compatibility

Currently, VRRP is only compatible with routed deployments.

VRRP Hardware Compatibility

VRRP requires network interface hardware on which DPDK PMDs support programming an additional MAC address. Without this capability, the interface cannot receive traffic addressed to the VRRP MAC address.

The following DPDK PMDs are supported:

  • em

  • fm10k

  • i40e

  • iavf

  • ice

  • igb

  • ixgbe

  • mlx4

  • mlx5

  • virtio

VRRP and Reflect ACLs

As there is not a method for VRRP cluster nodes to share dataplane ACL state data, using reflect type ACLs may result in active connections being dropped when control is transferred between cluster nodes. New connections may be made immediately.

Tip

Consider using VPF instead of dataplane ACLs, as it supports HA state synchronization (VPF High Availability).

VRRP and AWS/Azure

Currently, VRRP does not support unicast peers for routed environments such as AWS and Azure. This functionality will be added in a future release.
