Multi-level PNNI Topology
The first byte of the peer group ID indicates the peer group's level. It also indicates
Note
the number of significant bits used in the peer group ID. For example, if the level
indicator is 50 (80 decimal), then 80 bits / 8 = 10 bytes; and only 10 of the 13 bytes
are significant (39:00:00:00:00:00:00:00:00:00). If you create a new peer group
ID, make sure that the bytes you change are within the range of significant bytes
for the peer group's level.
