Syntax: [no] next-hop-mpls [compare-lsp-metric]
Changing the metric for an LSP
In the next example, the metric for LSP to2 is changed to a value (20) that causes the system to
remove it from the routing table, so only LSP to2_sec to 10.8.8.1/32 remains. This output
illustrates this result.
Brocade(config-mpls)# lsp to2
Brocade(config-mpls-lsp-to2)# disconnect
Disconnecting signaled LSP
Brocade(config-mpls-lsp-to2)# metric 20
Brocade(config-mpls-lsp-to2)# enable
Connecting signaled LSP to2

Disabling LSP-metric compare and checking the consequences
For the last example related to next-hop MPLS, disable LSP-metric compare using the no form of
the next-hop-mpls command and include the compare-lsp-metric option.
NOTE
When the user employs the no form with the optional compare-lsp-metric parameter for the
next-hop-mpls command, only this optional parameter is deleted, so global next-hop-mpls enable
remains the same. To disable both the optional LSP-metric compare and the global next-hop-mpls,
use the [no] form of the next-hop-mpls command without the optional parameter.
