VRRP Command Reference
256 7705 SAR OS Router Configuration Guide
With each consecutive attempt to send an ICMP echo request message, the timeout timer is started.
The timer decrements until:
• an internal error occurs preventing message sending (request unsuccessful)
• an internal error occurs preventing message reply receiving (request unsuccessful)
• a required route table entry does not exist to reach the IP address (request unsuccessful)
• a required ARP entry does not exist and ARP request timed out (request unsuccessful)
• a valid reply is received (request successful)
If an ICMP echo reply message is not received prior to the timeout period for a given ICMP echo
request, that request is considered to be dropped and the consecutive message drop counter is
incremented for the priority event.
If an ICMP echo reply message with the same sequence number as an outstanding ICMP echo request
message is received prior to that message timing out, the request is considered successful. The
consecutive message drop counter is cleared and the request message no longer is outstanding.
If an ICMP echo reply message with a sequence number equal to an ICMP echo request sequence
number that had previously timed out is received, that reply is silently discarded while incrementing
the priority event reply discard counter.
The no form of the command reverts to the default value.
Default 1
Parameters seconds — specifies the amount of time before an ICMP echo request message is timed out. Once
a message is timed out, a reply with the same identifier and sequence number is discarded.
Values 1 to 60

Syntax less-specific [allow-default]
no less-specific
Context config>vrrp>policy>priority-event>route-unknown
Description This command allows a CIDR shortest-match hit on a route prefix that contains the IP route prefix
associated with the route unknown priority event.
The less-specific command modifies the search parameters for the IP route prefix specified in the
route-unknown priority event. Using this command allows a CIDR shortest-match hit on a route prefix
that contains the IP route prefix.
Note: A required ARP request can succeed or time out after the message timeout timer
expires. In this case, the message request is unsuccessful.
