As per my understanding, DS TE tunnel will look for sub-pool bandwidth on every interface via RSVP. And this works fine when the entire path is configured with appropriate DiffServ QoS scheduling. So the traffic forwarded via DS-TE is like normal TE tunnel. i.e. either via Static routing, Policy Based Routing or Autoroute announce.
But below are my requirements in my case:
There are two nodes A and B. There exists two different paths (Path 1 and Path 2) to reach between them and I have normal TE tunnel via Path 1 and DS-TE tunnel via Path 2. From the tunnel head end (i.e. Node-A) I would like to forward packets marked with Precedence 5, 6 and 7 via DS-TE tunnel (via Path 2) and the rest of the traffic will be forwarded via Path 1. Is it possible to do this kind of routing.
Hope im clear in my understanding.
thanks in advance.
Can you post the configuration for the 3 tunnels.
The master tunnel is only required on platforms running 12.2SR code. That would include 7600 running 12.2SRA, SRB or SRC.
It is simply a logical decoupling, which makes you configure the exp values on the member tunnels and the routing information (autoroute announce, forwarding adjacencies, static route, PBR, etc) on the master tunnel.
