Configuring MPOA and NHRP Services

1-6

The remote MPOA router generates an NHRP address resolution reply

containing the ATM address provided by the MPS. Standard routing protocols

move the NHRP reply through the network to the local MPOA router.

The local MPOA router sends the resolved address to the MPS, which then

caches and sends the resolved address to the MPC that initiated the resolution

process.

10.

The local MPC caches the address resolution information and establishes an

SVC to the remote MPC, establishing the network cut-through connection for

more efficient communication.

Note again that in Figure 1-2, the logical connection between any two MPSs can

be an ATM PVC or RFC 1577 SVC (ATM Classical IP) instead of an ELAN,

depending on your network topology requirements.
