Special provisioning considerations for inter-ring hub node of OPE virtual rings or OPE ring spanning Layer 1 subtending rings

In the case where you provision an RPR spanning multiple Layer 1 (SONET) rings (see Figure 2-20 on page 2-41and Figure 2-21 on page 2-42), the hub node will require the use of two IPTR ring names for each RPR, to distinguish the two pass-through connections from one another. Two different provisioning scenarios and their cross-connect provisioning rules are listed in Table 2-5and Table 2-6.

Note: "first RPR" and "IPTR-1" represent the next time you provision an RPR on the hub node.
