A.If no SRv6 TE Policy is matched, select the SRv6 TE Policy with the default priority of this address family.

B.As shown in Figure 1 above, the available bandwidth of TE tunnels for all links is 1G. Blue indicates priority 1 tunnels (the solid line is the primary and the dotted line is the backup), occupying 60OM bandwidth. The remaining available bandwidth of the link is 40OM

C.The tunnel supports different priorities (0, 7), 0 indicates the highest priority, and 7 indicates the lowest priority. When a high-priority tunnel does not have a suitable path during path calculation, it can preempt a low-priority tunnel. That is, the bandwidth of the primary and secondary paths of high-priority tunnels is deducted, but the bandwidth of the secondary paths of high-priority tunnels can be shared by low-priority tunnels.

D.As shown in Figure 2, creating a tunnel with priority 2 requires a bandwidth of 50OM. In dynamic bandwidth mode, when both the primary and secondary high-priority tunnels are up, the bandwidth of the secondary path can be shared by the low-priority tunnel. , so the tunnel with priority 2 is still considered to be able to use 1G on the link RT1-RT2-RT4-RT3, so the path calculation can be successful. As shown in Figure 2, purple is a tunnel with priority 2 and bandwidth 500M.

E.As shown in Figure 3, when the path from RT1 to RT3 fails, because the main path has no way to go, the blue tunnel backup path is enabled. Since 50OM bandwidth has been occupied by purple, the remaining bandwidth of the 1G link is only 500M. The remaining bandwidth of the blue tunnel is only 500M. The colored tunnel can only use the remaining 50OM bandwidth. Insufficient bandwidth cannot be preempted from the low-priority purple tunnel where services have been deployed.
