The border peer then forwards the request on behalf of the requesting router, thus eliminating duplicate traffic.

Routing Table => Best Route Basic Management Setup ( basic management established ) Cisco routers to establish mode. only CCNA classroom streamlined notes Network connection. 0x1 Router will load the mini ios software and enter BOOT mode. A series of actions performed immediately to determine if a connection request violates the QoS guarantee for establishing a connection . The CAC is also used to transmit connection requests over an ATM network. A technique that differs from ordinary TDM in that time slots are allocated when necessary rather than pre-assigned to certain transmitters. Compare FDM , statistical multiplexing, and TDM . Crankback (in case of busy return ) In ATM , when a node cannot accept a connection somewhere on the selected path 0x2 Router will load the Flash in the IOS software . (Default config regcode) helper address ( help address ) specified unicast address, which directs Cisco router into direct end-to-end VLANs ( end the VLAN) ----- across the switch fabric (switch-fabric) from end to end The PPP protocol is defined in RFC 1378 .

AppleTalk----Apple Communications Corporation is a communication protocol suite designed for use in the Macintosh environment. There are currently two versions. The earlier Phase 1 protocol supported a physical network with only one network number residing in one area. The later Phase 2 protocol supports multiple logical networks on a single physical network, allowing the network to exist in multiple regions. See zone .
