A Frame Relay Backup Group is one or more DLCIs (on the same RLP) that can act
as a backup for one or more "primary" DLCIs (also on the same RLP). If a node
detects a failure in a primary DLCI connection, the software will search the backup
group configured for the primary DLCI, and will select the first available DLCI in that
group as a backup. The backup will become operational and will remain in that state
until the primary becomes active again. If the backup fails while in use, the software
will check the status of the primary, then (if necessary) search the primary's backup
group for another backup.
Any sessions in progress when a primary DLCI goes down will not be
transferred directly to the backup DLCI, but will be reset, then established
on the backup.
