Specifying the VT Interfaces Used by VPLS Routing Instances
By default, the Junos OS automatically selects one of the virtual tunnel (VT) interfaces available to the router for de-encapsulating traffic from a remote site. The Junos OS cycles through the currently available VT interfaces, regularly updating the list of available VT interfaces as new remote sites are discovered and new connections are brought up. However, you can also explicitly configure which VT interfaces will receive the VPLS traffic.
By including the tunnel-services statement at the [edit routing-instances routing-instance-name protocols vpls] hierarchy level, you can specify that traffic
for particular VPLS routing instances be forwarded to specific VT
interfaces. Doing so allows you to load-balance VPLS traffic among
all the available VT interfaces on the router.
The tunnel-services statement includes the following
options:
devices—Specifies the VT interfaces acceptable for use by the VPLS routing instance. If you do not configure this option, all VT interfaces available to the router can be used for de-encapsulating traffic for this instance.primary—Specifies the primary VT interface to be used by the VPLS routing instance. The VT interface specified is used to de-encapsulate all VPLS traffic from the MPLS core network for this routing instance. If the VT interface specified is unavailable, then one of the other acceptable VT interfaces (specified in the devices option) is used for handling the VPLS traffic. If you do not configure this option, any acceptable VT interface can be used to de-encapsulate VPLS traffic from the core.
In the VPLS documentation, the word router in terms such as PE router is used to refer to any device that provides routing functions.
To specify that traffic for a particular VPLS routing instance
be forwarded to specific VT interfaces, include the tunnel-services statement:
tunnel-services { devices device-names; primary primary-device-name; }
These statements can be configured at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls][edit logical-systems logical-system-name routing-instances routing-instance-name protocols vpls]
