Class-Based Tunnel Selection

Hi . Why would I have to add the tunnel mpls traff exp-bundle for CBTS to work?


  • If you have multiple tunnels in between same headend to tailend then you can forward traffic coming in from different customers( based on differernt CoS values) onto different tunnels.

    lets say u have tunnel1 that is having low latency, then surely u wanna forward VOICE traffic over it.

    and normal data traffic over other regular tunnels.

    So to acheive that we will map CoS values to different exp values then forward traffic based on exp values to different tunnels. Finally make the master tunnel visible by autoroute annouce feature.

    Use show mpls traffic-eng exp  for seeing exp mappings
