To enable and disable AHB forwarding on the router, complete the following
tasks:
Setting the Auto Learn Method
You can determine the method by which AHB automatically learns new bridge
entries on the router by configuring the auto learning method. You can configure
AHB in one of the following learning modes:
•Secure
• Unsecure
•Both
•None
By default, the auto learn method is set to Both. This means that AHB will learn
new bridge entries either securely or unsecurely.
If you set the learning mode to Secure or Both, AHB learns new bridge entries
from the DHCP reply packets sent on the AHB-configured interface. Entries
learned in secure mode always take precedence over entries learned in unsecure
mode.
If you set the learning mode to Unsecure or Both, AHB learns new bridge entries
from IP and ARP packets received on the AHB-configured interface.
