hop hop-index ip-address {strict | loose}
no hop hop-index
config>router>mpls>path
Supported on all 7210 SAS platforms as described in this document
This command configures the IP address of the hops that the LSP should traverse on its way to the egress router. The IP address can be the interface IP address or the system IP address. If the system IP address is specified, the LSP can choose the best available interface.
Optionally, the LSP ingress and egress IP address can be included as the first and the last hop. A hop list can include the ingress interface IP address, the system IP address, and the egress IP address of any of the hops being specified.
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 shut down first to delete the hop from the hop list. The no hop hop-index command results in no action except a warning message on the console indicating that the path is administratively up.
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.
Specifies the system or network interface IP address of the transit router. The IP address can be the interface IP address or the system IP address. If the system IP address is specified, the LSP can choose the best available interface. A hop list can also include the ingress interface IP address, the system IP address, and the egress IP address of any of the specified hops.
Keyword that specifies the route taken by the LSP from the previous hop to this hop can traverse through other routers. Multiple hop entries with the same IP address are flagged as errors. Either the loose or strict keyword must be specified.
Keyword that specifies 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 system IP address is specified, 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. Multiple hop entries with the same IP address are flagged as errors. Either the loose or strict keyword must be specified.

config>router>mpls
Supported on all 7210 SAS platforms as described in this document
This command configures a global parameter to apply a shorter retry timer for the first try after an active LSP path went down because of a local failure or the receipt of a RESVTear. This timer is used only on the first try. Subsequent retries continue to be governed by the existing LSP level retry timer.
0 (disabled)
Specifies the retry timer, in seconds.
[no] path path-name
config>router>mpls
Supported on all 7210 SAS platforms as described in this document
This command configures the path to be used for an LSP. A path can be used by multiple LSPs. A path can specify some or all hops from ingress to egress, and they can be either strict or loose. A path can also be empty (no path-name specified) in which case the LSP is set up based on IGP (best effort) calculated shortest path to the egress router. Paths are created in a shutdown state. A path must be shut down before making any changes (adding or deleting hops) to the path. When a path is shut down, any LSP using the path becomes operationally down.
To create a strict path from the ingress to the egress router, the ingress and egress routers must be included in the path statement.
The no form of this command deletes the path and all its associated configuration information. All the LSPs that are currently using this path are affected. All the services that are actively using these LSPs are also affected. A path must be shutdown and unbound from all LSPs using the path before it can be deleted. The no path path-name command results in no action except a warning message on the console indicating that the path may be in use.
Specifies a unique case-sensitive alphanumeric name label for the LSP path, up to 32 characters.
[no] shutdown
config>router>mpls>path
Supported on all 7210 SAS platforms as described in this document
This command disables the existing LSPs using this path. All services using these LSPs are affected. Binding information, however, is retained in those LSPs. Paths are created in the shutdown state.
The no form of this command administratively enables the path. All LSPs where this path is defined as primary or as standby secondary are established or re-established.
