Configuring IPX Routing Commands
As mentioned earlier in this chapter, you enable IPX routing with the global configuration command ipx routing. After IPX routing is enabled, the router builds the routing table used for routing. By default, when an IPX address is configured on a LAN or WAN interface and that interface is placed in an operational state, the IPX network address for that interface is placed in the routing table. All operational interfaces connected to the router are placed in the routing table...
AppleTalk Addressing and Address Structure
"TCP/IP Basics"—is described as an open protocol, AppleTalk is a proprietary protocol controlled by Apple Computers. AppleTalk has a unique network address structure and a unique naming methodology for network services. This section explores the AppleTalk network address structure that all clients (also called workstations) and servers must have to communicate within an AppleTalk internetwork. The AppleTalk network address is a 24-bit address consisting of two distinct co..
When mainframe computers dominated the industry, user terminals attached either directly to ports on the computer or to a controller that gave the appearance of a direct connection. Each wire connection was dedicated to an individual terminal. Users entered data, and the terminal immediately transmitted signals to the host. Performance was driven by the horsepower in the hosts. If the host became overworked, users experienced delays in responses. Note, though, that the connec..
Creating an Encrypted Router-to-Router VPN in a GRE Tunnel
There are several steps to these configurations, but they are the same on both routers. The first step is to create an appropriate key exchange policy using ISAKMP. The following set of commands defines the policy with priority 10. When ISAKMP negotiates the security association (SA) parameters, it starts with the lowest priority and goes to the highest. The highest possible priority value is 10,000: Router1(config)#crypto isakmp policy 10 Router1(config-isakmp)#encr aes 256..
Redistributing Static Routes into OSPF
To redistribute static routes into an OSPF process, use the redistribute static configuration command: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z.Router1(config)#ip route 192.168.10.0 255.255.255.0 172.22.1.4Router1(config)#ip route 172.24.1.0 255.255.255.0 172.22.1.4Router1(config)#ip route 10.100.1.0 255.255.255.0 172.22.1.4Router1(config)#router ospf 55Router1(config-router)#redistribute static % Onl..
