Task Remarks
Enabling the trap function Optional
You can configure an NNI interface in the same way a DCE interface is configured. For the configuration
procedure, see "Configuring DCE side frame relay."
If one endpo
int of a link is an NNI interface, the peer endpoint must also be an NNI interface.

Configuring frame relay address mappings
Configure frame relay address mappings in one of the following ways:
• Manually create static mappings between remote IP addresses and local DLCIs. Use this method
when the network topology is relatively stable and no new users are expected in a certain period
of time. Because static mappings do not change, the network connections are stable, and attacks
from unknown users are avoided.
• Use InARP to dynamically create mappings between peer IP addresses and local DLCIs. Use this
method in complicated networks and make sure the peer device also supports InARP.
