Configuring MPLS-TP
Page 92 7450 ESS MPLS Guide
The allowed values are as follows:
• wait-to-restore interval: 0-720 seconds, 1 sec steps, default 300 seconds. This is
applicable to revertive mode only.
• rapid-psc-timer interval: [10, 100, 1000ms]. Default 100ms
• slow-psc-timer interval: 5s-60s. Default: 5s
• revertive: Selects revertive behavior. Default: no revertive.
LSP Linear Protection operations are enacted using the following tools>perform commands.
tools>perform>router>mpls
tp-tunnel
clear {<lsp-name> | id <tunnel-id>}
force {<lsp-name> | id <tunnel-id>}
lockout {<lsp-name> | id <tunnel-id>}
manual {<lsp-name> | id <tunnel-id>}
exit
exit
To minimize outage times, users should use the “mpls-tp protection command” (e.g. force/manual)
to switch all the relevant MPLS-TP paths before executing the following commands:
• clear router mpls interface <>
• config router mpls interface <> shut
Intermediate LSR Configuration for MPLS-TP LSPs
The forward and reverse directions of the MPLS-TP LSP Path at a transit LSR are configured
using the following CLI tree:
config
router
mpls
mpls-tp
transit-path <path-name>
[no] path-id {lsp-num <lsp-num>|working-path|protect-path
[src-global-id <global-id>]
src-node-id {<ipv4address> | <1.. .4,294,967,295>}
src-tunnel-num <tunnel-num>
[dest-global-id <global-id>]
dest-node-id {<ipv4address> | <1.. .4,294,967,295>}
[dest-tunnel-num <tunnel-num>]}
forward-path
in-label <in-label> out-label <out-label>
out-link <if-name> [next-hop <ipv4-next-hop>]
reverse-path
in-label <in-label> out-label <out-label>
[out-link <if-name> [next-hop <ipv4-next-hop>]
[no] shutdown
