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:
VRRP and NAT¶
VRRP may not be used on interfaces involved in outbound NAT when the VR
255. Currently there is an interaction between NAT and VRRP in
this case which leads to both nodes failing to receive and process VRRP
advertisements from peers. When NAT is present on outbound NAT interfaces, use a
lower priority value. Conflicting configurations will be rejected by input
See the recipe VRRP with Outside NAT for a compatible example configuration.
VRRP and Reflect ACLs¶
As there is not yet a method for VRRP cluster nodes to share 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
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.
