Specify both the physical and logical portions of the interface name, in the following format:
-
physical.logical
For example, in ge-1/2/1.2, ge-1/2/1 is the physical portion of the interface name and 2 is the logical portion. If you do not specify the logical portion of the interface name, 0 is set by default.
A logical interface can be associated with only one routing instance.
If you enable a routing protocol on all instances by specifying interfaces all when configuring the master instance of the protocol at the [edit protocols] hierarchy level, and you configure a specific interface for VPLS routing at the [edit routing-instances routing-instance-name] hierarchy level, the latter interface statement takes precedence and the interface is used exclusively for VPLS.
If you explicitly configure the same interface name at both the [edit protocols] and [edit routing-instances routing-instance-name] hierarchy levels and then attempt to commit the configuration, the commit operation will fail.
