Quick Steps for Configuring a Protect-Swap Label-Map
The following steps assume that a label-map swap next-hop action for label 777 is already configured on
the transit router. The protect-swap configures an alternate next-hop path that FRR will use if the primary
path configured for label 777 is down.
1 On the transit router where the next-hop segment to protect originates, configure a protect-swap action
using the configure router mpls interface label-map protect-swap next-hop command. For example:
-> configure router mpls interface vlan-10 label-map 777 protect-swap 778 next-
hop 192.168.11.2
The above command swaps label 777 out of the label stack and replaces it with label 778 and then forwards
the packet to the next-hop router (192.168.11.2).
2 By default, the MPLS label-map is administratively disabled. To enable the label-map, use the
configure router mpls interface label-map shutdown command with the no shutdown option. For
example, the following command enables the label-map associated with MPLS interface “vlan-10”:
-> configure router mpls interface vlan-10 label-map 777 no shutdown
