ARP packetsto determinethe IPXnetwork onthe other endof the vir-

tual circuit. If the IARP is responded to, a route is placed in the IPX

route table. A setting of No means that the IPX network is to be as-

to be transmitted out a particular bridge group are copied and trans-

mitted individually out each DLCI in the bridge group. However, in-

coming bridge packets received from one DLCI are not retransmitted

out the other DLCIs in the same bridge group. Any device in the

bridge group must transmit to each DLCI. This requires a fully
