AA transit IP and transit prefix policies

Transit subscriber discovery

AA transit IP and transit prefix policies define how AA transit subscribers are created by an NE. Transit IP policies can be configured to discover dynamic transit subscribers via DHCP or RADIUS, and can also be configured with a list of static transit subscribers. Transit IP policies can also be configured to discover dynamic transit subscribers when traffic is detected on a parent SAP or spoke SDP binding.

Transit prefix policies allow you to specify transit subscribers by using network or subscriber IP ranges.

AA transit subscribers can persist in the NFM-P database. Transit subscriber aggregators allow you to aggregate multiple database persisted transit subscriber instances for VPN sites.

Because of the potentially high rate at which AA transit subscribers are created and deleted, a throttling mechanism is available on the NE for the associated creation and deletion traps. See To configure trap throttling for AA transit subscriber creation and deletion .
