above example, c1 and c2 are the equipment of PU2.0 type, and c3 is the 
equipment of PU2.1 type.
Diagnosis and 
Troubleshooting of 
DLSw FaultThe normal communication of DLSw requires the sound coordination between the 
two SNA equipments and two routers operating DLSw, which participate in the 
communication. Problem in the co-ordination between any of the two points is 
likely to result in failure in connection.
Fault 1: TCP channel can not be created. The status shown...

communication can be implemented after you activate SDLC line manually.

IP ROUTING PROTOCOL
IP Routing Protocol 
OverviewRouters are used to select the route in the Internet. A router selects a suitable path 
according to the destination host address contained in a received data packet, and 
sends the data packet to the next router. The last router on the path sends the 
data packet to the destination host.
Route and Route 
SegmentA router processes the path for transmitting a packet through a network as a 
logical route unit, referred to as a hop. For example, in 
Figure...

of the router should be used to transfer a data packet to a sub-network or a host, 
so the packet can reach the next router on this path, or reach the host as a directly 
connected destination without passing through other routers.
The routing table consists of the following key items:
■Destination address: Identifies the destination address or destination 
network of IP packets.
■Network mask: Identifies, together with the destination address, the address 
of the route...
