routing-instance

(Optional) Uses the routing instance you specify for the traceroute.

routing-instance-name

 

source address

(Optional) Uses the source address that you specify, in the traceroute packet.

tos number

(Optional) Sets the type-of-service (TOS) value in the IP header of the traceroute packet. Specify

 

a value from 0 through 255.

0 through 128.

wait seconds

(Optional) Sets the maximum time to wait for a response.
