LDP over RSVP (for transit LSR only)

By default, LDP tunneling is disabled. The user must disable the LSP configuration to change the
setting on the ldp-tunneling command.
NOTE
The ldp-tunneling command is not available under bypass LSP configuration.
To disable IS-IS shortcuts or OSPF shortcuts, enter the [no] form of the command.
The level1 or level2 keyword is required and indicates the level of IS-IS routing enabled on the
device. The levels are:
•
level1 – A level1 router routes traffic only within the area that includes the router. To forward
traffic to another area, a level1 router sends the traffic to the nearest level2 router.
•
level2 – A level2 router routes traffic between areas within a domain.
The LDP tunneling configuration is displayed in the output of the show mpls lsp command. When
LDP tunneling is enabled, the line reads “yes.” When it is not enabled, the line reads “no.”
Brocade(config-mpls)# show mpls lsp blue
LSP blue, to 10.20.20.20

The LDP tunneling configuration is also displayed in the output of the show mpls config command,
and the show mpls config lsp command. In the following example, LDP tunneling with IS-IS
shortcuts is enabled.
