Configuring an IETF DS-TE Tunnel Using RDM
Perform this task to create an IETF mode DS-TE tunnel using RDM.
Before You Begin
The following prerequisites are required to create an IETF mode DS-TE tunnel using RDM:
•
You must have a router ID for the neighboring router.
•
Stable router ID is required at either end of the link to ensure that the link is successful. If you do not
assign a router ID to the routers, the system defaults to the global router ID. Default router IDs are subject
to change, which can result in an unstable link.
