Maintaining MPLS TE

Checking Connectivity of a TE Tunnel

The connectivity of a TE tunnel between the ingress and egress is checked.

Checking a TE Tunnel Using NQA

After configuring MPLS TE, you can use Network Quality Analysis (NQA) to check the connectivity and jitters of a TE tunnel.

Checking Tunnel Error Information

If an RSVP-TE tunnel interface is Down, run display commands to view information about faults.

Deleting RSVP-TE Statistics

A reset command is used to delete RSVP-TE statistics.

Resetting the RSVP Process

Resetting the RSVP process triggers a node to re-establish all RSVP CR-LSPs or verify the RSVP process.

Deleting an Automatic Bypass Tunnel and Re-establishing a New One

If MPLS TE Auto FRR is enabled, a command is used to instruct a node to tear down an automatic bypass tunnel and reestablish a new one.

Deleting PCEP Session Statistics

PCEP session statistics can be deleted manually.

Loopback Detection for a Specified Static Bidirectional Co-Routed CR-LSP

Loopback detection for a specified static bidirectional co-routed CR-LSP locates faults if a few packets are dropped or bit errors occur on links along the CR-LSP.

Enabling the Packet Loss-Free MPLS ECMP Switchback

The packet loss-free MPLS ECMP switchback can be enabled.
