timeout
Syntax timeout seconds

Context config>vrrp vrrp-policy-id>priority-event>host-unreachable ip-addr
Description This command defines the time, in seconds, that must pass before considering the far-end IP host
unresponsive to an outstanding ICMP echo request message.
The timeout value is not directly related to the configured interval parameter. The timeout value may
be larger, equal, or smaller, relative to the interval value.
If the timeout value is larger than the interval value, multiple ICMP echo request messages may be
outstanding. Every ICMP echo request message transmitted to the far end host is tracked individually
according to the message identifier and sequence number.
With each consecutive attempt to send an ICMP echo request message, the timeout timer is loaded with
the timeout value. 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).
