When deploying HPE Aruba VSX switches parallel to existing HPE Comware switches, choosing a first-hop redundancy protocol compatible with both platforms is essential. VRRP (Virtual Router Redundancy Protocol) is widely supported across multiple vendors and is suitable for multi-vendor environments.
HSRP is Cisco proprietary and not supported on Aruba Comware or CX.
Active Forwarding and Active Gateway are Aruba VSX internal mechanisms, not standard first-hop redundancy protocols.
VRRP provides seamless failover and is supported in Comware and Aruba CX platforms.
Thus, VRRP is the suitable choice.
