15.1.5 Accept mode

The virtual router, unless it is the IP address owner, does not reply to the packets sent to the virtual IP address even if it is the master. In general, however, such a virtual router will check the status of network devices by pinging them.

The switch supports an accept mode. In accept mode, the master virtual router can reply to the packets sent to the virtual IP address. Even if the master virtual router is not the IP address owner, you can use the vrrp accept configuration command to specify accept mode and allow the master virtual router to receive ICMP Echo Request packets and send ICMP Echo Reply packets. This command allows you to check the status of VRRP routers externally.
