Why each option

For vEdge router redundancy in Cisco SD-WAN, VRRP is the supported standards-based First Hop Redundancy Protocol.

AHSRP

HSRP (Hot Standby Router Protocol) is a Cisco proprietary FHRP and is not supported on vEdge routers for providing first-hop redundancy.

BOMP

OMP (Overlay Management Protocol) is the routing protocol used within the Cisco SD-WAN overlay fabric for exchanging routing and policy information, and it is not a First Hop Redundancy Protocol.

CGLBP

GLBP (Gateway Load Balancing Protocol) is a Cisco proprietary FHRP designed for load balancing, and it is not supported on vEdge routers for redundancy.

DVRRPCorrect

When designing redundancy for vEdge routers, VRRP (Virtual Router Redundancy Protocol) is the supported standards-based First Hop Redundancy Protocol (FHRP) that provides default gateway redundancy for connected endpoints.
