The following commit command makes the new parameter settings active in Adaptive LSP to20’s
configuration
Brocade(config-mpls)# lsp to20
Brocade(config-mpls-lsp-to20)# commit
Syntax: [no] commit
After the commit command runs, the user can see that the priorities have changed by using the
show mpls lsp command for lsp to20.
Brocade(config-mpls-lsp-to212)# show mpls lsp to212

Reoptimizing LSPs
Under ordinary conditions, an LSP path does not change unless the path becomes inoperable.
Consequently, the router needs to be directed to consider configuration changes made to an LSP
and to optimize the LSP path based on those changes. This is accomplished using the mpls
reoptimize command as shown in the following.
Brocade# mpls reoptimize lsp to20
Syntax: [no] mpls reoptimize all | lsp lsp-name
