Statement introduced in Junos OS Release 12.3.
Specify a preference for the interface to become the designated forwarder (DF) for a
multihomed VPLS site. This
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.
