MPLS and RSVP-TE
Parameters
include — allows an RSVP-TE LSP to be used as a transport LSP from the ASBR to a
exclude — blocks an RSVP-TE LSP from being used as a transport LSP from the ASBR
cspf
Syntax
[no] cspf [use-te-metric]
Context
config>router>mpls>lsp
config>router>mpls>lsp-template
Description
This command enables Constrained Shortest Path First (CSPF) computation for constrained-
path LSPs. Constrained-path LSPs are the LSPs that take configuration constraints into
account. CSPF is also used to calculate the FRR bypass or detour LSP routes when fast
reroute is enabled.
Explicitly configured LSPs where each hop from ingress to egress is specified do not use
CSPF. The LSP is set up using RSVP-TE signaling from ingress to egress.
If an LSP is configured with fast-reroute specified but does not enable CSPF, neither global
revertive nor local revertive will be available for the LSP to recover.
When an LSP template is created, CSPF is automatically enabled and cannot be disabled.
Default
no cspf
Parameters
use-te-metric — specifies to use the TE metric for the purpose of the LSP path
default-path
Syntax
default-path path-name
Context
config>router>mpls>lsp-template
Description
This command specifies the default path to be used for signaling an LSP created using the
LSP template. You must reference a default path before the template is put in a no shutdown
state.
Parameters
path-name — specifies the default path name to be used
