Configuring a Forward GMPLS UNI Tunnel

Configuring a Forward GMPLS UNI Tunnel

A GMPLS UNI tunnel is unidirectional. A forward GMPLS UNI tunnel and a reverse GMPLS UNI tunnel must be established to implement bidirectional traffic transmission. The ingress EN initiates tunnel establishment requests containing tunnel attributes. Therefore, basic tunnel attributes and functions must be configured on the ingress EN.

Context

Forward and reverse UNI-LSPs are established for bidirectional GMPLS UNI tunnels and have the same requirements on traffic engineering. A GMPLS UNI tunnel is established using extended RSVP-TE. The ingress EN initiates tunnel establishment requests containing tunnel attributes by sending Path messages. Therefore, tunnel attributes and functions need to be configured on the ingress EN and do not need to be configured on the egress EN for a reverse GMPLS UNI tunnel.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run gmpls-tunnel gmpls-tunnel-name

    A GMPLS UNI tunnel is established, and the tunnel view is displayed.

  3. Run tunnel-id tunnel-id

    The tunnel ID is configured.

  4. Run destination ip-address

  5. Run bandwidth bw-value

    The bandwidth is configured for the GMPLS UNI tunnel.

  6. Run explicit-path path-name

    Explicit path constraints are configured.

  7. Run switch-type { dcsc | evpl }

    A data switching type is set for a GMPLS UNI tunnel.

  8. Run bind interface interface-type interface-number

    A GMPLS UNI tunnel interface is bound to a service interface.

    Only a local GMPLS UNI can function as a service interface.

  9. (Optional) Run link protection-type unprotected

    The link protection function is configured for the GMPLS UNI tunnel.

    If PCE path calculation is configured, this command does not need to be run. This is because the device forcibly sets the protection type to rerouting for PCE path calculation.

  10. Run commit

    The configuration is committed.
