Matching AS_SET and AS_CONFED_SEQ
Example 13-5 shows how to use a BGP filter list to match the AS_SET and AS_CONFED_SEQ segment types. Figure 13-5 depicts the specifics of the example. In this case, R4 summarizes 16.0.0.0/4, creating an AS_SET entry for the summary, and advertising it to R1 and R3. R1 and R3 in turn advertise the route to R2; R1’s route includes an AS_CONFED_SEQ, because R1 and R2 are confederation eBGP peers. Figure 13-5 Generating AS_SET and AS_CONFED_SEQ Example 13-5 shows two ..
Pure multipoint Enhanced IGRP divides the configured bandwidth evenly across each virtual circuit. However, you must ensure that this does not overload each virtual circuit. The formula for multipoint is as follows: Bandwidth × number of VC (virtual circuits) For example, if you have an access line speed of T1 and there are four virtual circuits, each with 56 Kbps CIR, the bandwidth should be set to 4 × 56 Kbps = 224 Kbps. This will ensure that p..
Using SNMP to Copy a New IOS Image
Before you can upload or download the router's IOS image to a TFTP server, you have to set up a valid read-write SNMP community string: Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#snmp-server community ORARW rw Router(config)#end Then you can download a copy of your router's current IOS file to your TFTP server with the following Unix commands: Freebsd% touch /tftpboot/c2600-jk9o3s-mz.122-7a.bin Freebsd% chmod ..
The Cisco IOS software only supports the Frame Relay SVC feature on a Cisco router as a DTE device. The Frame Relay switching enhancement feature currently does not support SVC switching functionalities. Presently, only PVC switching is supported. There are commercial Frame Relay switches by different vendors that support Frame Relay SVC switching. Check with your service provider about SVC support when ordering a Frame Relay SVC circuit. Frame Relay SVC is supported on both..
Verifying Frame Relay Connections with IOS show Commands
Many Cisco IOS commands that are supported on Cisco routers can be used either to validate users' Frame Relay configuration command changes, to verify the status of the Frame Relay connection, or as a troubleshooting tool. For instance, the show frame-relay map command displays the remote network address to local DLCI mapping and indicates the remote network destinations reachable via the connected Frame Relay network. This section looks at the general IOS show commands most ..
