standby-forwarding
Syntax [no] standby-forwarding
Context config>router>if>vrrp
Description This command specifies whether this VRRP instance allows forwarding packets to a standby router.
When disabled, a standby router should not forward traffic sent to virtual router's MAC address.
However, the standby router should forward traffic sent to the standby router’s real MAC address.
When enabled, a standby router should forward all traffic.
telnet-reply
Syntax [no] telnet-reply
Context config>router>if>vrrp
Description This command enables the non-owner master to reply to TCP port 23 Telnet requests directed at the
virtual router instances’ IP addresses.
Non-owner virtual router instances are limited by the VRRP specifications to responding to ARP
requests destined to the virtual router IP addresses and routing IP packets not addressed to the virtual
router IP addresses. Many network administrators find this limitation frustrating when
troubleshooting VRRP connectivity issues.
This limitation can be disregarded for certain applications. Ping, SSH and Telnet can each be
individually enabled or disabled on a per-virtual-router-instance basis.
The telnet-reply command enables the non-owner master to reply to Telnet requests directed at the
virtual router instances’ IP addresses. The Telnet request can be received on any routed interface.
Telnet must not have been disabled at the management security level (either on the parental IP
interface or based on the Telnet source host address). Proper login and CLI command authentication
is still enforced.
When telnet-reply is not enabled, Telnet requests to non-owner master virtual IP addresses are
silently discarded.
Non-owner backup virtual routers never respond to Telnet requests regardless of the telnet-reply
setting.
The telnet-reply command is only available in non-owner vrrp nodal context.
By default, Telnet requests to the virtual router instance IP addresses will be silently discarded.
The no form of the command configures discarding all Telnet request messages destined to the non-
owner virtual router instance IP addresses.
Default no telnet-reply - Telnet requests to the virtual router instance IP addresses are discarded.
