Balancing Between Two Routers Sharing Multiple Paths
This section shows how load balancing can be achieved between two routers sharing multiple paths without having routing updates being duplicated over the two paths. For the scenario in Figure 12-6, you will configure loopback interfaces on RTA and RTC (see Example 12-22 and Example 12-23) and run a single peering session between the two routers. Using static routes, you can point to the loopback interfaces via both of the physical interfaces. This way, the IP routing table wi..
Verifying AppleTalk Connectivity and Troubleshooting
The IOS software offers numerous tools to aid the network administrator in tracking down AppleTalk connectivity problems, network configuration errors, and dynamic routing protocol problems. In this section, we examine IOS EXEC show commands, debug commands, and diagnostic commands that facilitate identifying network issues. As previously examined, the IOS EXEC command show appletalk interface is a useful tool for identifying network number and zone name misconfigurations, a..
The IOS software found on Cisco routers and other devices has dozens of features to aid in the operation of the network and of the router itself. In this section, we examine four features commonly implemented on the router that enhance network operation and ease the use of the router itself. Configuring Domain Name Services In TCP/IP networks today, most people refer to servers, printers, workstations, and other IP devices by their names rather than by their IP addresses. R..
You can use the following configuration command to adjust a router's SNMP trap timeout value: Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#snmp-server trap-timeout 60 Router(config)#end Router# To adjust a router's SNMP inform timeout value, use the follow configuration commands: Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#snmp-server inform timeou..
TCP is a connection-oriented transport protocol that sends data as an unstructured stream of bytes. By using sequence numbers and acknowledgment messages, TCP can provide a sending node with delivery information about packets transmitted to a destination node. Where data has been lost in transit from source to destination, TCP can retransmit the data until either a timeout condition is reached or until successful delivery has been achieved. TCP can also recognize duplicate me..
