SRv6 TE Policy Load Balancing

The SRv6 TE Policy model is the same as the SR-MPLS TE Policy model, as shown in Figure 1. One SRv6 TE Policy may contain multiple candidate paths with the preference attribute. The valid candidate path with the highest preference functions as the primary path of the SRv6 TE Policy.

A candidate path can contain multiple segment lists, each of which carries a Weight attribute. Each segment list is an explicit SID stack that instructs a network device to forward packets, and multiple segment lists can work in load balancing mode.
