Cisco CRS Configuration Guide

Before you can successfully bring optical TE tunnels “up,” you must complete the procedures in the
preceding sections.
Note
The following characteristics can apply to the headend (or, signaling) router:
•
Tunnels can be numbered or unnumbered.
•
Tunnels can be dynamic or explicit.
The following characteristics can apply to the tailend (or, passive) router:
•
Tunnels can be numbered or unnumbered.
•
Tunnels must use the explicit path-option.
Configuring an Optical TE Tunnel Using Dynamic Path Option
Perform this task to configure a numbered or unnumbered optical tunnel on a router; in this example, the
dynamic path option on the headend router. The dynamic option does not require that you specify the different
hops to be taken along the way. The hops are calculated automatically.
The examples describe how to configure optical tunnels. It does not include procedures for every option
available on the headend and tailend routers.
