When non-owner access Telnet is enabled on a virtual router instance, authorized Telnet sessions may be established that are destined for the virtual router instance IP addresses when operating in master mode. Telnet sessions are always discarded at the IP interface when destined for a virtual router IP address operating in backup mode. Enabling non-owner access Telnet does not guarantee Telnet access; correct management and security features must be enabled to allow Telnet on this interface and possibly from the specified source IP address.
When 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.
