Configuring RSVP-TE
All configured primary and secondary paths for the
endpoint IP address. For example, three paths can be configured for the
but all paths should represent different topological paths through the network to the
same LSP endpoint.
Adding a secondary

Provided the

<lsp_name>
chosen. If at any time the primary path is established,
switches to using the primary path. If a secondary path fails while in use, the remaining
configured secondary paths can become the active path for
To delete a path from an RSVP-TE LSP, use the following command:
config mpls rsvp-te lsp <lsp_name> delete path <path_name>
When you issue this command, the LSP associated with the path is immediately torn
down. If the deleted path represents the in-use LSP for
secondary path is configured, the LSP immediately fails over to an alternate LSP.
Because at least one path must be defined for each LSP, the last configured path cannot
be deleted from the LSP.
Displaying RSVP-TE LSP Configuration Information
To display RSVP-TE LSP configuration information, use the following command:
show mpls rsvp-te {<ipaddress>} {detail}
This command displays information about the status of RSVP-TE enabled interfaces.
Summary information is displayed for all known RSVP-TE peers including the peer IP
address and peer status. If you specify the
information for a single RSVP-TE interface is displayed. Additional information is
displayed in the detailed format if you specify the optional
detailed RSVP-TE information includes the number and type of RSVP messages
transmitted through the local RSVP-TE interface.
