With the need to continuously expand my skill set I've been playing around in a HP Comware lab and looking at First-hop Redundancy Protocols. These allow for the protection of the default gateway used by a subnet. FHRPs generally work in an active/standby mode. When the active network device fails, or is taken down for maintenance, the standby router will take over.
The example below shows how to configure Virtual Router Redundancy Protocol between two HP Comware devices.
[R1]interface GigabitEthernet 0/0 [R1-GigabitEthernet0/0]ip address 192.168.0.252 24 [R1-GigabitEthernet0/0]vrrp vrid 1 virtual-ip 192.168.0.254 [R1-GigabitEthernet0/0]vrrp vrid 1 priority 254 [R2]interface GigabitEthernet 0/0 [R2-GigabitEthernet0/0]ip address 192.168.0.253 24 [R2-GigabitEthernet0/0]vrrp vrid 1 virtual-ip 192.168.0.254 [R2-GigabitEthernet0/0]vrrp vrid 1 priority 100
When testing the failover speed, only a single ICMP packet was dropped.
