MPLS-TP identifiers are configured for a node under the following CLI tree:
config
router
mpls
mpls-tp
global-id <global-id>
node-id {<ipv4address> | | <1.. .4,294,967,295>}
[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 are configured, then it is recommended that the global ID should be set to the local ASN of the node, as configured under config>system. 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 brings down all of the MPLS-TP LSPs on the node. New values are propagated to the system when a no shutdown is performed.
