MPLS-TP identifiers are configured for a node under the following CLI tree.
config
router
mpls
mpls-tp
global-id <global-id>
node-id <node-id>
[no] shutdown
exit
The default value for the global-id is 0. This is used if the global-id is not explicitly configured. If a user expects that inter domain LSPs will be configured, then it is recommended that the global ID should be set to the local ASN of the node. as configured under config>router. If two-byte ASNs are used, then the most significant two bytes of the global-id are padded with zeros.
The default value of the node-id is the system interface IPv4 address. The MPLS-TP context cannot be administratively enabled unless at least a system interface IPv4 address is configured because MPLS requires that this value is configured.
These values are used unless overridden at the LSP or PW end-points, and apply only to static MPLS-TP LSPs and PWs.
To change the values, config>router>mpls>mpls-tp must be in the shutdown state. This will bring down all of the MPLS-TP LSPs on the node. New values are propagated to the system when a no shutdown is performed.
