PNNI Internetworking with IISP

Interim Inter-Switch Protocol (IISP) is the predecessor to AINI and serves the same purpose as AINI, which is to link two independent PNNI networks. Unlike AINI, IISP does not support all UNI 4.0 features.

Note Standards-based IISP supports SVC and SVP connections. Cisco has enhanced IISP to also support CBR1, rt-VBR1, rt-VBR2, rt-VBR3, nrt-VBR1, nrt-VBR2, and ABR SPVC and SPVP connections.

If the border nodes between two independent PNNI networks support AINI, you should use AINI for any links between them. The only time you should use IISP is when one or both of the border nodes do not support AINI.
