accept-mode
A VRRP nonowner master router does not respond to any packet that is destined for the virtual IPv4 or IPv6 address.
VRID interface configuration mode
A VRRP nonowner master router does not respond to any packet that is destined for the virtual IPv4 or IPv6 address. This prevents troubleshooting network connections to this router using ping, traceroute, or Telnet. To resolve this, you can use this command to enable the router to respond to ping, traceroute, and Telnet packets destined for the virtual IPv4 or IPv6 address of a VRRP cluster. The router drops all other packets destined for the virtual IPv4 or IPv6 address of the VRRP session.
accept-mode command enables the device to respond to ping, traceroute, and Telnet packets, but
the device does not respond to SSH packets. When the device acting as the master router
is not the IP address owner (the router with the interface whose actual IP address
is used as the virtual router’s IP address), the master router accepts only the ARP
packets sent to the virtual IP address. When accept mode is configured, the master
router responds to ping, TELNET, and traceroute packets sent to the virtual IP address
even when the master router is not the IP address owner.
The
no form of the command causes the nonowner master router to not respond to any packet
that is destined for the virtual IPv4 or IPv6 address of the VRRP session.
The following example shows the configuration of accept mode on an IPv6 VRRP backup router.
device# configure terminal device(config)# interface ve 3 device(config-vif-3)# ipv6 vrrp vrid 2 device(config-vif-3-vrid-2)# backup device(config-vif-3-vrid-2)# advertise backup device(config-vif-3-vrid-2)# ipv6-address 2001:DB8::1 device(config-vif-3-vrid-2)# accept-mode device(config-vif-3-vrid-2)# activate
