Policy Routing Based on Traffic Source/Destination
Policy routing can also be based on a source/destination combination, as illustrated in Figure 8-7. Figure 8-7. Policy Routing Scenario Based on Source and Destination Assume that RTA wants to use the SF link for any traffic originating from network 10.10.10.0/24 and reaching network 12.12.12.0/24 in NY. Also, RTA wants to use the SJ link for any traffic originating from network 10.10.10.0/24 and reaching network 13.13.13.0/24 in NY. Policy routing can be used to set t..
The Cisco IOS CLI includes several methods to get help at the CLI. Many of you already use these features out of habit, but for completeness, the full set of features is listed in Table 24-7. Table 24-7 Cisco IOS Software Command Help 1command represents any command, not the word command. Likewise, parm represents a command’s parameter, not the word parameter. 2When you type the?, the Cisco IOS CLI reacts immediately; that is, you don’t need to press the Enter k..
Simple Network Management Protocol
SNMP is an application layer protocol used to manage IP devices. SNMP is part of the TCP/IP application layer suite. SNMP enables network administrators to view and change network parameters and monitor connections locally and remotely. Managing network performance over a period of time is one of the major functions that SNMP provides. There are three versions of SNMP: • SNMP Version 1 (SNMPv1) • SNMP Version 2 (SNMPv2) • ..
The solution to this problem is similar to the RIP solution. First we have to enable the routing protocol on the CE routers, which we do in the usual way: Router-CE-A1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router-CE-A1(config)#router eigrp 156 Router-CE-A1(config-router)#network 192.168.1.0 Router-CE-A1(config-router)#network 192.168.5.0 Router-CE-A1(config-router)#no auto-summary Router-CE-A1(config-router)#end Router-C..
Changing the Network Type on an Interface
OSPF supports several different types of logical networks on interfaces. The default values are often exactly what you want, but it is sometimes useful to change them: Router9#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router9(config)#interface FastEthernet0/0 Router9(config-if)#ip ospf network ? broadcast Specify OSPF broadcast multi-access network non-..
