CRLSP backup

CRLSP backup uses a CRLSP to back up a primary CRLSP. When the ingress detects that the primary CRLSP fails, it switches traffic to the backup CRLSP. When the primary CRLSP recovers, the ingress switches traffic back.

CRLSP backup has the following modes:

• Hot standby—A backup CRLSP is created immediately after a primary CRLSP is created.

• Ordinary—A backup CRLSP is created after the primary CRLSP fails.
