VRRP Non-owner Accessibility

Although only VRRP owners can respond to ping and other management-oriented protocols
directed to the VRID IP addresses, the 7705 SAR allows an override of this restraint on a
per-VRRP virtual router instance basis.
This section contains information on the following topics:

Non-owner Access Ping Reply

If non-owner access ping reply is enabled on a virtual router instance, ICMP echo request
messages destined for the non-owner virtual router instance IP addresses are not discarded at
the IP interface if the virtual router is operating in master mode. ICMP echo request messages
are always discarded in backup mode.
If non-owner access ping reply is disabled on a virtual router instance, ICMP echo request
messages destined for the non-owner virtual router instance IP addresses are silently
discarded in both the master and backup modes.

Non-owner Access Telnet

If non-owner access Telnet is enabled on a virtual router instance, authorized Telnet sessions
can be established that are destined for the virtual router instance IP addresses if the virtual
router is operating in master mode. Telnet sessions are always discarded at the IP interface if
destined for a virtual router IP address on a virtual router operating in backup mode. Enabling
non-owner access Telnet does not guarantee Telnet access; proper management and security
features must be enabled to allow Telnet on this interface and possibly from the given source
IP address.
If non-owner access Telnet is disabled on a virtual router instance, Telnet sessions destined
for the non-owner virtual router instance IP addresses are silently discarded in both master
and backup modes.
