A subsequent iteration of the show command in the bypass LSP context shows that this LSP is a
candidate for protection by a bypass LSP. The display for protected LSP xmr3-199 shows that,
under frr, the facility-backup line shows this protection is requested.

Brocade(config-mpls-bypasslsp-123)# show mpls config lsp xmr3-199

Specifying a bypass LSP

The user can create a bypass LSP by using the bypass-lsp command. Thereafter, in the bypass LSP
context, the user must specify at least one interface as an exclude (protected) interface. This
interface can be on a LAG. In this example, xm4 is specified to be a bypass LSP; the protected LSP
interfaces are specified; and then the options for a bypass LSP are displayed.

Brocade(config)# router mpls

Brocade(config-mpls)# bypass-lsp xm4-by

Brocade(config-mpls-bypasslsp-xm4-by)#

Brocade(config-mpls-bypasslsp-xm4-by)# exclude-interface e 1/2, e 1/2, e 2/5-e 2/8
