advertise-interval
Enterasys C3 Configuration Guide 27-33
Defaults
None.
Mode
Router configuration: C3(su)->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 to enable master ICMP replies on VLAN 1, VRID 1.
C3(su)->router(Config-router)#master-icmp-reply vlan 1 1
advertise-interval
Use this command to set the interval in seconds between VRRP advertisements. The no form of
this command clears the VRRP advertise interval value.
Syntax
advertise-interval vlan vlan-id vrid interval
no advertise-interval vlan vlan-id vrid interval
Parameters
Defaults
None.
Mode
Router configuration: C3(su)->router(Config-router)#
Usage
VRRP advertisements are sent by the master router to other routers participating in the VRRP
master selection process, informing them of its configured values. Once the master is selected,
vlan vlan-id Specifies the number of the VLAN on which to configure the VRRP
advertisement interval. This VLAN must be configured for IP routing as
described in “Pre-Routing Configuration Tasks” on page 24-1.
vrid Specifies a unique Virtual Router ID (VRID) associated with the routing
interface. Valid values are from 1 to 255.
interval Specifies a VRRP advertisement interval to associate with the vrid. Valid
values are from 1 to 255 seconds.
