Configuring Traffic Engineering Links and Data Bearers

Bearer link identifiers. The association between the Layer 2 interface address and the data

bearer must be correctly configured at the UNI-C and UNI-N. The show>router>lmp>te-link

command displays the local link ID, remote link ID, and associated port ID to assist with this.

The CLI tree for creating TE Links under LMP is as follows. Note that there are also some

RSVP-specific TE Link parameters that are configured under a separate gmpls context (see

The te-link-id can take the form of an unsigned integer or 64 character (max) name:

[1..2147483690] | te-link-name: 64 char max

Upon creation, only the unsigned integer needs to be specified. Once the link is created the

user can configure the link name (ie. 'link-name te-link-name'). From here, the user can refer

to this te-link by either the unsigned integer or the ASCII name.

Note that LMP will normally assume a data bearer is operationally up, even if no MAC layer

or a valid PCS IDLE stream is received. This is because a neighboring UNI-N may not

generate a PCS IDLE stream and instead transparently transports the MAC layer from the far

end, which won't be up unless a gLSP is configured. In order to prevent LMP from using a

port for which there is a local fault on the data bearer, indicated by loss of light, a user must

configure report-alarm on the Ethernet port, as follows:

config>port>ethernet>report-alarm signal-fail

Only ports with report-alarm signal-fail configured can be included in LMP, and that

report-alarm signal-fail cannot be subsequently removed from a port in LMP.

RSVP requires that all traffic engineering attributes for TE Links are configured under the

config>router>gmpls>te-link context.
