Configuring the VPLS Site Preference

You can specify the preference value advertised for a particular VPLS site. The site preference value is encoded in the BGP local preference attribute. When a PE router receives multiple advertisements with the same VPLS edge (VE) device identifier, the advertisement with the highest local preference value is preferred.

To configure the VPLS site preference, include the site-preference statement:




site-preference preference-value;

You can also specify either the backup option or the primary option for the site-preference statement. The backup option specifies the preference value as 1, the lowest possible value, ensuring that the VPLS site is the least likely to be selected. The primary option specifies the preference value as 65,535, the highest possible value, ensuring that the VPLS site is the most likely to be selected.

For a list of hierarchy levels at which you can configure the site-preference statement, see the statement summary section for this statement.
