MPOA

• The Multi Protocol Over ATM (MPOA) deals with the efficient transfer of inter-subnet unicast data in a LANE environment

• MPOA integrates LANE and NHRP to preserve the benefits of LAN Emulation

• Inter-subnet IP traffic is carried over ATM VCs without involving routers in the data path

• MPOA provides a framework for synthesizing bridging and routing in an ATM environment supporting:

  • various protocols
  • various network technologies
  • IEEE 802.1Q VLANs

• MPOA uses both routing and bridging information to determine the optimal exit point from the ATM network
