Since very early days of RSVP-TE one fundamental recommendation we were giving operators was to always do policing/rate-limiting what goes into a TE-LSP on ingress. There is nothing more or less perfect about it - it is either in place or not. Such policing/rate-limiting would also auto adjust when auto-bandwidth has been enabled. So if the unexpected traffic entered the network it was either dropped or shaped on ingress. You are talking about unpredicted load suddenly appearing in the middle of the network and NOT as a result of already single network failure. I guess you are still confirming that you will not protect with TTE traffic which is already protected with vanilla FRR due to node/link failure. Regards, R.
