Configuring Mpls Te Tunnel With Dynamic Signaling Protocol - H3C SR8800 10G Mpls Configuration Manual

static-cr-lsp ingress command, you must input its name in the form of Tunnel2. Otherwise, your tunnel
establishment attempt will fail. This restriction however does not apply to transit and egress nodes.

Configuring MPLS TE tunnel with dynamic signaling
protocol
Dynamic signaling protocol can adapt the path of a TE tunnel to network changes and implement
redundancy, FRR, and other advanced features.
The following describes how to create an MPLS TE tunnel with a dynamic signaling protocol:
• Configure MPLS TE properties for links and advertise them through IGP TE extension to form a TEDB.
Configure tunnel constraints.
•
Use the CSPF algorithm to calculate a preferred path based on the TEDB and tunnel constraints.
•
Establish the path by using the signaling protocol RSVP-TE or CR-LDP.
