Configuring the VPLS Site Interfaces

You must configure an interface for each of the pseudowires you specify for the VPLS
site.
To configure an interface for the VPLS site, include the
interface interface-name {
interface-mac-limit limit;
}
You can include these statements at the following hierarchy levels:
[edit routing-instances routing-instance-name protocols vpls site site-name]
[edit logical-systems logical-system-name routing-instances routing-instance-name
protocols vpls]
You can also configure a limit on the number of MAC addresses that can be learned from
the specified interface. For more information, see
Learned from an Interface" on page

Configuring the VPLS Site Preference

You can specify the local preference value advertised for a particular VPLS site. The site
preference value is specified using the
routing-instances routing-instance-name protocols vpls site site-name]
configuring the
site-preference
statement at the [edit protocols bgp]
instance. However, you can change the site preference value for VPLS routes exported
to other routers by configuring an export policy. 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 preference-value {
backup;
primary;
}
You can also specify either the
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
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 include the
