Master-Icmp-Reply - Enterasys Matrix DFE-Gold Series Configuration Manual

master-icmp-reply

Example
This example shows how set a VRRP priority of 200 on VLAN 1, VRID 1:
Matrix>Router(config)#router vrrp
Matrix>Router(config-router)#priority vlan 1 1 200
master-icmp-reply
Use this command to enable ICMP replies for non‐owner masters.
Syntax
master-icmp-reply vlan vlan-id vrid
no master-icmp-reply vlan vlan-id vrid
Parameters
vlan vlan‐id
vrid
Defaults
None.
Mode
Router command, Router configuration: Matrix>Router(config‐router)#
Usage
This command provides the ability for the virtual router master to respond to an ICMP echo even
if it does not "own" the virtual IP address. Without this function, the virtual router can only
respond to an ICMP echo when the virtual IP address matches the real IP address of the interface.
Therefore, when the backup router takes over, there would be no device that would answer the
ICMP echo for that virtual IP (because only the primary was configured with the matching real
IP). With master‐icmp‐reply enabled, management stations that use "ping" to poll devices will be
able to "see" that the virtual router is available when the backup router assumes the role of master.
The "no" form of this command disables master ICMP replies.
Example
This example shows how enable master ICMP replies on VLAN 1, VRID 1:
Matrix>Router(config)#router vrrp
Matrix>Router(config-router)#master-icmp-reply vlan 1 1
Specifies the number of the VLAN on which to enable master ICMP
replies. This VLAN must be configured for IP routing as described in
"Reviewing and Configuring Routing" on page 2‐101.
Specifies a unique Virtual Router ID (VRID) associated with the routing
interface. Valid values are from 1 to 255.
