FIGURE 117 Example 2 multiple rings sharing interfaces - phase 2
Ring interface IDs and types
For example, in Figure 118 , all interfaces configured for ring 1 have a priority of 1. Interface e 1/1
on S1 and e 2/2 on S2 have a priority of 1 since 1 is the highest priority ring that shares the
interface.
All interfaces on ring 2, except for e 1/1 on S1 and e 2/2 on S2 have a priority of 2.
If a node has shared interfaces then the ring interfaces that belong to the ring with the highest
priority are regular interfaces for that ring and all lower priority ring interfaces are marked as tunnel
interfaces. The highest priority ring configured becomes the priority for the interface.
