maxttl specifies the maximum time-to-live, or
maximum number of routers the traceroute packet will traverse.
The vrfid argument
specifies which VRF to send the traceroute packets from. You can
get a list of available VRFs with the
get logical-routers command.
The source argument specifies which source IP
address to use for traceroute. This may be required in some
circumstances for traceroute to work as expected. For example,
if there is overlap in IP addresses used in the tier 0 and
tier 1 router transit subnets, traceroute packets from the
tier 0 VRF will not reach virtual machines on networks routed
by the tier 1 router. If you use the source argument
to specify a unique IP used by that VRF (in this case, the tier 0
uplink IP) the traceroute packets will reach the virtual machines.
