The CLI syntax for this configuration is:
config>router>mpls>lsp lsp-name>fast-reroute facility
If the LSP from A to D goes through Node B and bypass is requested, the
next hop is Node C, and there is a manually configured bypass-only tunnel
from B to C that excludes link BC (that is, path BEFC), then Node B uses
the bypass-only tunnel.
The following example displays a bypass tunnel configuration output.
A:ALU-48>config>router>mpls># info
-------------------------------------------
...
path "BEFC"
hop 10 10.10.10.11 strict
hop 10 10.10.10.12 strict
hop 10 10.10.10.13 strict
no shutdown
exit
lsp "bypass-BC" bypass-only
to 10.10.10.15
primary "BEFC"
exit
no shutdown

3.20.8 Configuring RSVP-TE Parameters and Interfaces
RSVP-TE is used to set up LSPs. RSVP-TE must be enabled on the router interfaces
that are participating in signaled LSPs. The default values can be modified in the
config>router>rsvp context.
Initially, interfaces are configured in the config>router>mpls>interface context.
Only these existing (MPLS) interfaces are available to be modified in the
config>router>rsvp context. Interfaces cannot be directly added in the rsvp
context.
The following example displays an RSVP-TE configuration output.
A:ALU-1>config>router>rsvp# info
----------------------------------------------
keep-multiplier 3
refresh-time 30
no msg-pacing
rapid-retransmit-time 5
rapid-retry-limit 3
