Configuration overview

About this task

The following steps must be performed to configure MPLS-TP LSPs or PWs.

At the 7210 SAS LER and LSR:

Procedure

  1. Create an MPLS-TP context, containing nodal MPLS-TP identifiers. This is configured under config>router>mpls>mpls-tp.
  2. Ensure that a sufficient range of labels is reserved for static LSPs and PWs. This is configured under config>router>mpls-labels>static-labels.
  3. Ensure that a range of tunnel identifiers is reserved for MPLS-TP LSPs under config>router>mpls-mpls-tp>tp-tunnel-id-range.
  4. A user may optionally configure MPLS-TP interfaces, which are interfaces that no not use IP addressing or ARP for next hop resolution. These can only be used by MPLS-TP LSPs.

What to do next

At the 7210 SAS LER, configure:

  1. OAM Templates. These contain generic parameters for MPLS-TP proactive OAM. An OAM template is configured under config>router>mpls>mpls-tp>oam-template.

  2. BFD templates. These contain generic parameters for BFD used for MPLS-TP LSPs. A BFD template is configured under config>router>bfd>bfd-template.

  3. Protection templates. These contain generic parameters for MPLS-TP 1-for-1 linear protection. A protection template is configured under config>router>mpls>mpls-tp>protection-template.

  4. MPLS-TP LSPs are configured under config>router>mpls>lsp mpls-tp

  5. Pseudowires using MPLS-TP are configured as spoke SDPs with static PW labels.

At an LSR, the user must configure an LSP transit-path under config>router>mpls>mpls-tp>transit-path.

The following sections describe these configuration steps in more detail.
