PNNI Routing Multi-level PNNI Topology
Do the same on switch SWB3:
B3 # set pnnipglelection
NodeIndex(1) :
LeadershipPriority(0) : 205
< Highest priority in election process
ParentNodeIndex(0) : 2
< Node 2 will represent the peer group B in the parent group
InitTime(15) :
OverrideDelay(30) :
ReElectTime(15) :
B3 #
7. Use the show pnnipglelection command to verify that switches SWA3 and SWB3 have become
the PGLs of their respective peer groups. For example, on switch SWA3, enter the following:
A3 # show pnnipglelection
NodeIndex(1) :
PGL Election Information
================================================================================
Node Index : 1
Leadership Priority : 100
Parent Node Index : 2
Init Time : 15 secs
Override Delay : 30 secs
Reelect Time : 15 secs
Time Stamp : 228588
Election State : Operating as PGL
< Switch SWA3 has become PGL of group A
Preferred PGL : 50:a0:39:00:00:00:00:00:00:00:00:00:a3:87:0b:00:20:d4:28

8. Physically connect switch SWA3 to SWB3 to establish connectivity between peer groups A and B.
9. Use the show pnnilink command to check the connectivity between the peer groups. In the
following example,
show pnnilink is entered on switch SWA3 and shows a link to switch SWB3
(SWB3’s IP address is 206.61.237.23):
A3 # show pnnilink
Num(ALL) :

3 7B1 1 206.61.237.23 CommonOut Outside and Uplink
< Physical link to switch SWB3
4 -- 2 N/A 2WayInside Horizontal Link to/from LGN
< Logical link between the switches

Note Notice that the IP address entry for the logical link between the LGNs is N/A (Not
Applicable). Logical entities do not have IP addresses.
