When the sid-label parameter is specified, this command specifies an MPLS label value for
a hop in the path of an SR-TE LSP. The label value implied by the SID is only used when the
path is used by an SR-TE LSP. The loose and strict options do not apply for a hop containing
a SID label; a SID hop must always be strict.
When the IP address is specified, the hop must be configured as either loose or strict. The
loose option specifies that the route taken by the LSP from the previous hop to this hop can
traverse other routers. The strict option specifies that the LSP must take a direct path from
the previous hop router to this router. No transit routers between the previous router and this
router are allowed. If the IP address specified is the interface address, that is the interface the
LSP must use. If there are direct parallel links between the previous router and this router and
if the system IP address is specified, then any one of the available interfaces can be used by
the LSP. The user must ensure that the previous router and this router have a direct link. For
both options, multiple hop entries with the same IP address are flagged as errors.
The no form of this command deletes hop list entries for the path. All the LSPs currently using
this path are affected. Additionally, all services actively using these LSPs are affected.
The path must be first shut down in order to delete the hop from the hop list. The
no hop hop-index command does not result in any action other than generating a warning
message indicating that the path is administratively up.
Default n/a
Parameters hop-index — specifies the hop index, which is used to order the specified hops. The LSP
always traverses from the lowest hop index to the highest. The hop index does not
need to be sequential.
Values 1 to 1024
ip-address — specifies the system, loopback, or network interface IP address of the
transit router
sid-value — specifies any valid MPLS/SR label value. The value is not restricted by any
locally defined label ranges.
Values 32 to 1048575
strict — specifies that the LSP must take a direct path from the previous hop router to
this router. No transit routers between the previous router and this router are allowed.
loose — specifies that the route taken by the LSP from the previous hop to this hop can
traverse other routers
