Configuring Annex G
Optional
Marking the DE bit
Optional
Configuring frame relay fragmentation
Optional
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 endpoi
nt 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.
