When vEdge router redundancy is designed, which FHRP is supported?
When Cisco SD-WAN edge router redundancy is designed, VRRP is the supported first-hop redundancy protocol in the SD-WAN edge context. VRRP provides a virtual default gateway for LAN-side devices, allowing one WAN Edge router to act as the active gateway while another can take over if the active router or tracked condition fails. Cisco SD-WAN designs use VRRP with tracking and policy alignment so branch LAN traffic can fail over to the appropriate edge router while the SD-WAN overlay handles transport and tunnel selection. HSRP and GLBP are traditional campus first-hop redundancy protocols, but they are not the supported FHRP answer for vEdge router redundancy in this design context. OMP is the SD-WAN control-plane routing protocol used between WAN Edge routers and vSmart controllers; it is not a first-hop redundancy protocol for LAN hosts. Therefore, the correct FHRP for vEdge router redundancy is VRRP. The design should also ensure that VRRP priorities, tracking, and SD-WAN routing preferences align so traffic exits the intended edge during normal and failure conditions.
