Setting PNNI peer group ID
Use the following command to set the PNNI peer group ID.
Setting PNNI peer group ID to default value
Use the following command to set the PNNI Peer Group ID to its default value. The
default value is derived from the PNNI level and the switch’s prefix. The first byte
of the peer group ID is the level indicator. The following bytes must be prefixes of
ATM End System Addresses as defined in the PNNI specification (af-pnni-
0055.000). The peer group is encoded with the 104-n rightmost bits set to zero,
where n is the level.
PNNI PGLE Parameters
The Peer Group Leader Election (PGLE) submenu is important in hierarchical
PNNI, where this protocol takes place while electing the PGL. The most important
parameter here is the Leadership Priority, which indicates the priority of each node
for becoming a PGL. Leadership Priority of 0 indicates that the node will not
become a PGL.
Command: M15-155s8:/>route pnni config pg_id set <level>
< pg id >
Parameters level (1-5) Internal level number: 1 is the lowest (physical)
node
pg id 14 hexadecimal bytes separated by a decimal. The
first byte is the level (1-104 in Hex). 104-level
rightmost bits should be zero.
Output: Warning: This request will change the peer group id. It will
also change the node level and the first byte of the node id to
<level scope in hex>.

Command: M15-155s8:/>route pnni config pg_id default <level>
Output: This request will set default value (extracted from ATM
address) for peer group id.
