bypass (Signaled LSP)


Hierarchy Level


Enables you to configure specific bandwidth and path constraints for a bypass LSP. It is possible to individually configure multiple bypass LSPs. If you do not configure the bypass LSPs individually, they all share the same path and bandwidth constraints.

If you specify the bandwidth, hop-limit, and path statements for the bypass LSP, these values take precedence over the values configured at the [edit protocols rsvp interface interface-name link-protection] hierarchy level. The other attributes (subscription, no-node-protection, and optimize-timer) are inherited from the general constraints.



(Required) Specify a name for the bypass LSP. The name can be up to 64 characters.


Provides a textual description of the bypass LSP. Enclose any descriptive text that includes spaces in quotation marks (" "). Any descriptive text you include is displayed in the output of the show mpls lsp bypass detail command and has no effect on the operation of the bypass LSP. The description text can be no more than 80 characters in length.

subscription subscription-percentage

(Optional) Specify the subscription percentage per manual bypass LSP. The subscription percentage configured under a particular manual bypass LSP overrides the subscription percentage configured commonly for all manual bypass LSPs under an interface.

  • Range: 0 through 65000

to address

(Required) Specify the address for the interface of the immediate next-hop node (for link protection) or the next-next-hop node (for node-link protection). The address specified determines whether this is a link protection bypass or a node-link protection bypass. On multiaccess networks (for example, a LAN), this address is also used to specify which next-hop node is being protected.

The remaining statements are explained separately. See CLI Explorer.
