74.2.10 IP Destination Reachability
The following describes IP Destination Reachability commands.
74.2.10.1 track
This command is used to define a tracking destination to be used by static routes or other
configured elements. The configured track is testing the reachability of the defined destination
through the defined source interface by sending probe packets to the destination and wait for
replies.
Syntax
track <track id> {icmpecho | icmp6echo} <destination address>
<source interface> <interface ID> [source-ip-interface
<interface>] [interval <value>] [retries <value>]
Command Description
icmpecho Tracking is done by sending ICMP probes and monitors the
replies.
icmpv6echo Tracking is done by sending ICMPv6 probes and monitors the
replies
track id Defines the track identifier to be used by other entities.
track protocol type Defines the reachability by sending ping packets of either IPv4
or IPv6 (currently only probe type).
destination address
Defines the ip address of the tracked destination in the format of
a.b.c.d for IPv4 and X:X::X:X for IPv6.
source interface Defines the interface name and ID.
source IP interface
Defines an interface whose IP address is used as the source ip
address for the probes.
interval <value>
Defines the option to define interval between probes in seconds
Range is 1-3600. (Default value is 5 seconds).
retries <value> Defines the option to define retries of probes before track state
is moved to “down”. Range is 0 – 20. (Default value is 3).
