Restoring Auto-Summary on the LGN SanFran
After all the nodes destined for the new peer group migrate into the peer group, you can restore
auto-summary to reduce the number of reachable address prefixes advertised by the LGN.
auto-summary to reduce the number of reachable address prefixes advertised by the LGN.
The following example shows how to enable auto-summary on the LGN SanFran:
SanFran.BldA.T5# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
SanFran.BldA.T5(config)# atm router pnni
SanFran.BldA.T5(config-atm-router)# node 2
SanFran.BldA.T5(config-pnni-node)# auto-summary
SanFran.BldA.T5(config-pnni-node)# end
SanFran.BldA.T5#
The following example shows how to verify the configuration:
SanFran.BldA.T5# show atm pnni summary
Codes: Node - Node index advertising this summary
Type - Summary type (INT - internal, EXT - exterior)
Sup - Suppressed flag (Y - Yes, N - No)
Auto - Auto Summary flag (Y - Yes, N - No)
Adv - Advertised flag (Y - Yes, N - No)

2 Int N Y N 47.0091.4455.6677.2233/72
The switch that contains the active PGL is configured similarly:
SanFran.BldA.T4# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
SanFran.BldA.T4(config)# atm router pnni
SanFran.BldA.T4(config-atm-router)# node 2
SanFran.BldA.T4(config-pnni-node)# auto-summary
SanFran.BldA.T4(config-pnni-node)# end
SanFran.BldA.T4#
