To summarize, during a GR recover, the LSP information is preserved for the forwarding plane and 
therefore MPLS packets can be forwarded without interruption. 

You need to configure MPLS basic capability on all routers for MPLS forwarding within an MPLS domain, 
and to configure MPLS basic capability before configuring any other MPLS features. 

 

Currently, only VLAN-interface supports MPLS capability. 

 

Before configuring MPLS basic capability, be sure to complete these tasks: 

z

 

Configuring physical parameters on relevant interfaces, 

z

 

Configuring link layer attributes on relevant interfaces, 

z

 

Assigning IP addresses to relevant interfaces, 

z

 

Configuring static routes or an IGP protocol, ensuring that LSRs can reach each other at Layer 3. 

 

MPLS basic capability can be configured on LSRs even when LSRs cannot reach each other. However, 
you need to configure the mpls ldp transport-address command in this case. For details about the 
command, refer to MPLS Basics Commands in the MPLS Volume. 

 

Follow these steps to configure MPLS basic capability: 

Enter system view 

— 

Configure the MPLS LSR ID
