Configuring MPLS functions
Configuring MPLS LDP functions globally and on all interfaces
Data
Type and number of the interface on which the backup LSP is set up
Type and number of the interface on which the timer is configured
Timer value
When OSPF runs as an IGP, do as follows on the interfaces of both ends of the link between
the crossing node of the active link and the standby link and the LDP neighboring node on
the active link:
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
ospf ldp-sync
Synchronization between LDP and OSPF is enabled on the interface to be protected.
When IS-IS runs as an IGP, do as follows on the interfaces of both ends of the link between
the crossing node of active and standby links and the LDP neighboring node on the active
link:
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
