Migrating from E-IISP to PNNI
In order to migrate successfully to PNNI, the network manager must
review the network address scheme that will be used. There are two
possible approaches to implementing address change:
■
Deriving a PNNI peer group ID and peer group level based on the E-IISP
addressing scheme. See Chapter 3 in the Operations Guide for
information on E-IISP addressing.
■
Changing the E-IISP network prefixes to match the PNNI addressing
scheme.
The gateway between E-IISP and PNNI must be between the E-IISP
highest level and the PNNI gateway node.
