Redistribution Using Default Settings
The first example configuration meets the following design goals: ■ R1 redistributes between each pair of IGPs—RIP, EIGRP, and OSPF. ■ Default metrics are used whenever possible; when required, the metrics are configured on the redistribute command. ■ Redistribution into OSPF uses the non-default subnets parameter, which causes subnets to be advertised into OSPF. ■ All other settings use default values. Example 11-1 shows R1’s configuration for each routing..
External BGP (EBGP) neighbors are usually directly connected. In Figure 8-13, you configure EBGP between Routers A and B and investigate the operation and configuration of EBGP neighbors. Figure 8-13. Configuring EBGP The first step in configuring EBGP is to configure a loopback interface on Routers A and B. (See Example 8-2.) As with OSPF, the IP address assigned to the loopback interface is used as the BGP router ID. Example 8-2. Configuring Loopback Interfaces on Routers..
Reducing the Size of the Received Routing Table
For most typical Internet connections, you will need to drastically reduce the amount of routing information that you receive. A typical Internet backbone router needs to support BGP routes for well over 100,000 prefixes. So unless you are operating the ISP and need to support a large fraction of the public address space, it is a good idea to cut out as much as possible. It is important to remember that removing routing information means that some of your routing decisions wi..
Table 1-1 summarizes the common Frame Relay terminology you will continue to see throughout this book. Table 1-1. Common Frame Relay Terminology Term Definition Description CIR Committed Information Rate Rate in bps at which the network commits to transfer user data under normal conditions, averaged over a minimum time interval, Tc. EIR Excess Information Rate The maximum rate in bps in excess of the ..
Increasing the RIP Input Queue
To increase the size of the shared RIP queue, use the input-queue configuration command: Router2#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router2(config)#router rip Router2(config-router)#input-queue 200 Router2(config-router)#end Router2# This command allows you to control how much incoming RIP update information the router can hold before it has can process the information and integrate it into its routing table. Sometimes a ro..
