When the value of vRtrMplsLspFastReroute is 'true', fast reroute
is enabled. A pre-computed detour LSP is created from each node
in the primary path of this LSP. In case of a failure of a link
or LSP between two nodes, traffic is immediately rerouted on the
pre-computed detour LSP thus avoiding packet loss. Each node
along the primary path of the LSP tries to establish a detour LSP
as follows: Each upstream node will setup a detour LSP that
avoids only the immediate downstream node and merges back onto
the actual path of the LSP as soon as possible. The detour LSP
may take one or more hops (upto the value of vRtrMplsLspFRHopLimit)
before merging back onto the main LSP path.
When the upstream node detects a downstream link or node failure,
it immediately send traffic for that LSP on the detour path and
at the same time signals back to the ingress ESR about the
failure.
Fast reroute applies only to the primary path of this LSP.
No configuration is required on the transit hops of the LSP.
The ingress ESR will signal all intermediate ESRs using RSVP
to setup their detours.
When the value of vRtrMplsLspFastReroute is 'false', fast
rerouting is disabled.
