ProSafe Managed Switch
Ping to a VRRP IP address only works from the host side (where the VRRP router is
configured). There is no value in pinging to the VRRP IP from another interface because
packet flow from the network to the host doesn't involve VRRP. This is used only to
troubleshoot a connectivity problem for traffic originating on the VRRP protected LAN.
Members of the virtual router who are in backup state discard ping packets destined to VRRP
address(es), just as they discard any Ethernet frame sent to a VRRP MAC address. When
the VRRP master responds with an Echo Reply, the source IPv4 address is the VRRP
address and source MAC address is the virtual router's MAC address.
There is a separate command "ip icmp echo-reply" that controls whether the router responds
to ICMP Echo Requests. When Echo Replies are disabled using that command, the VRRP
master does not respond to Echo Requests, even if this new option is enabled.
