MPLS and RSVP
7210 SAS M, T, X, R6, Mxp MPLS Configuration Guide Page 141
In LDP-over-RSVP, LDP performs a lookup in the Routing Table Manager (RTM) which provides
the next hop to the destination PE and the advertising router (ABR or destination PE itself). If the
advertising router matches the targeted LDP peer, LDP then performs a second lookup for the
advertising router in the Tunnel Table Manager (TTM). This lookup returns the best RSVP LSP to
use to forward packets for an LDP FEC learned through the targeted LDP session. The lookup returns
the LSP with the lowest metric. If multiple LSPs have the same metric, then the result of the lookup is
to select the first one available in the TTM.
Default 1
Parameters metric — Specifies the metric for this LSP which is used to select an LSP among a set of LSPs which
are destined to the same egress router.
Values 1 — 65535
to
Syntax to ip-address
Context config>router>mpls>lsp
Description This command specifies the system IP address of the egress router for the LSP. This command is
mandatory to create an LSP.
An IP address for which a route does not exist is allowed in the configuration. If the LSP signaling
fails because the destination is not reachable, an error is logged and the LSP operational status is set
to down.
Default No default
Parameters ip-address — The system IP address of the egress router.
vprn-auto-bind
Syntax vprn-auto-bind [include | exclude]
Context config>router>mpls>lsp
Description This command determines whether the associated names LSP can be used or no as part of the auto-
bind feature for VPRN services. By default a names LSP is available for inclusion to used for the
auto-bind feature.
By configuring the command vprn-auto-bind exclude, the associated LSP will not be used by the
auto-bind feature within VPRN services.
The no form of the command resets the flag backto the default value.
Default include
Parameters include — Allows an associated LSPto be used by auto-bin for vprn services
exclude — Disables the use of the associated LSP to be used with the auto-bind feature for VPRN
services.
