MPLS Commands
configure mpls rsvp-te lsp add path
configure mpls rsvp-te lsp <lsp_name> add path <path_name> {<profile_name>}
{secondary | primary}
Description
Adds a path to an RSVP-TE LSP.
Syntax Description
Default
N/A.
Usage Guidelines
The
<lsp_name>
must represent a configured LSP. Only one primary path and up to two secondary
paths can be added per
<lsp_name>
. The
<path_name>
specified defaults to primary when no primary
path has been configured for
<lsp_name>
and defaults to secondary if the primary path has been
previously configured for
<lsp_name>
.
You do not need to configure the primary path for an LSP. Each
<path_name>
added to an
<lsp_name>
must be unique, but a
<path_name>
can be associated with multiple LSP names.
All configured primary and secondary paths for the
<lsp_name>
must have the same endpoint IP
address. For example, three paths can be configured for the
<lsp_name>
, but all paths should represent
different topological paths through the network to the same LSP endpoint.
Adding a secondary
<path_name>
designates a path as a hot-standby redundant path, used in the event
that the primary or secondary path cannot be established or fails. Provided the
<path_name>
has not
already been established, all
path names
are signaled as soon as they are associated with an
<lsp_name>
. If the primary
<path_name>
fails, is not configured, or cannot be established after the
specified LSP retry-timeout, one of the configured secondary paths may become the active path for
<lsp_name>
. All of the secondary paths have equal preference; the first one available is chosen. If at any
time the primary path is established,
<lsp_name>
immediately 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
<lsp_name>
.
Example
The following command adds a secondary path named paththroughdc for the specified LSP:
configure mpls rsvp-te lsp lsptonyc add path paththroughdc secondary
lsp_name Specifies the name of a configured LSP.
path_name Specifies the path name.
profile_name Specifies the profile name.
primary Specifies the primary path.
secondary Specifies a secondary path.
