MPLS TE - Record-route

[Guillaume Gryszata]

Hi,

Can you tell me what is the purpose of the "tunnel mpls traffic-eng record-route".

Just for information (to have the record route in any show command) or mandatory for a particular configuration?

Thx.

Guillaume,

This command is used to force the inclusion of additional information in the route record object of the RESV message. This information is only required for MPLS TE FRR (Node Protection). This command is enabled automatically when FRR is requested on the tunnel interface using the "tunnel mpls traffic-end fast-reroute" command.

Ok, I think it's uses for the PLR to have labels for the protected LSP to reache the MP.

Thanks for helping me.

Guillaume.

That is correct. The information is indeed used by the PLR to determine what label is used by the protected LSP on the merge point (MP).
