Selecting The Permanent Wan Link As The Primary Wan Connection - Nortel Enterprise Edge 2.0 Programming Manual

230 Configuring Enterprise Edge Services
Note: Net Link Manager manages the default route in Enterprise Edge. If a link
breaks, Net Link Manager removes all the default routes on the broken link
and adds them to the backup link. This happens during switch over from
primary to secondary link. The default routes return to the primary link after
the connection to the primary WAN link is reestablished.
To enable or disable Net Link Manager:
1. On the navigation tree, click Services then click Net Link Manager.
The Net Link Manager Summary screen appears.
The Summary screen attributes are:
