traceroute
Use the traceroute command to discover the routes that IPv4 or IPv6 packets actually
take when traveling to their destination through the network on a hop-by-hop basis.
Traceroute continues to provide a synchronous response when initiated from the CLI.
take when traveling to their destination through the network on a hop-by-hop basis.
Traceroute continues to provide a synchronous response when initiated from the CLI.
The user may specify the source IP address of the traceroute probes. Recall that traceroute
works by sending packets that are expected not to reach their final destination, but instead
trigger ICMP error messages back to the source address from each hop along the forward
path to the destination. By specifying the source address, the user can determine where
along the forward path there is no route back to the source address. Note that this is only
useful if the route from source to destination and destination to source is symmetric.) It would
be common, for example, to send a traceroute from an edge router to a target higher in the
network using a source address from a host subnet on the edge router. This would test
reachability from within the network back to hosts attached to the edge router. Alternatively,
one might send a traceroute with an address on a loopback interface as a source to test
reachability back to the loopback interface address.

In the CLI, the user may specify the source either as an IPv4 address, IPv6 address, or as a
routing interface. When the source is specified as a routing interface, the traceroute is sent
using the primary IPv4 address on the source interface. With SNMP, the source must be
specified as an address. The source cannot be specified in the web UI.
