Usage guidelines
Class Based Tunnel Selection (CBTS) compares the service class value of VXLAN packets with the
service class values of MPLS TE tunnels. CBTS uses the following rules to select a tunnel to forward
the traffic:
•
If the packets match only one MPLS TE tunnel, CBTS uses this tunnel.
•
If the packets match multiple MPLS TE tunnels, CBTS randomly selects one tunnel from them.
•
If the packets do not match any MPLS TE tunnel, CBTS selects the MPLS TE tunnel that meets
the following requirements:
Its service class value is smaller than the service class value of the traffic.

Its service class value is the nearest to the service class value of the traffic.

If multiple qualified tunnels exist, CBTS randomly selects one of them to forward the packets. If
an MPLS TE tunnel is not configured with a service class value, this tunnel has the smallest
service class value.
The service class value is used only when MPLS TE tunnels are used to forward the VXLAN packets.
This value is meaningless if any other tunnel is used to forward the VXLAN packets.
: Specifies a service class value. The value range for this argument is 0
