[j-nsp] MPLS FRR and EXP bits

[Eduardo Barrios]

Hello List,

I was told that the EXP bits do not carry over during a fast reroute event that is configured for Facility many-to-one (ie a bypass tunnel).  So essentially the third label in the stack is the RSVP tunnel setup by the point of local repair and it does not carry the EXP QoS markings of the second label (transport label).

Is this true? Just concerned that important traffic that is FRR protected by the bypass tunnel and "in flight" might not get treated with the appropriate QoS levels.

Any thoughts on this?

Thanks,
Eduardo
