preference (Interface-Level Preference for VPLS Multihoming for FEC 129)


Hierarchy Level


Specify a preference for the interface to become the designated forwarder (DF) for a multihomed VPLS site. This preference statement can be useful when you want the interface preference for a site to change dynamically so that the DF election can be influenced depending on the interface state. Among the list of interface preferences, Junos OS advertises the best preference as the VPLS site’s preference value. For example, if the site has three interfaces configured with preference values 12, 10, and 9, respectively, 12 is advertised as the site preference. If that interface goes down, 10 is advertised as the site preference.

If you configure interface-level preference, you cannot configure site-level preference.
