Examples: Configuring Link Services Interfaces

This example shows only the link services part of the configuration. To see the T1 configuration options, see the JUNOS Network Interfaces Configuration Guide.

The examples in this section show the following configurations:

This configuration initiates the MLFR UNI NNI protocol between Router A and Router B and logically connects link services bundles ls-1/1/0.3 and ls-0/0/0.10, as specified in Table 24.

Table 24: Link Services Bundle

Router A

Router B

t1-0/1/0 (ls-1/1/0:3)

t1-0/3/0 (ls-0/0/0:10)

t1-0/1/1 (ls-1/1/0:3)

t1-0/3/1 (ls-0/0/0:10)

For LMI to work properly, you must configure one router to be a DCE.

Configuring a Link Services Interface with Two Links
