Table 10-4 lists the LSA types and their descriptions for reference; following the table, each type is explained in more detail, in the context of a working network. Table 10-4 OSPF LSA Types Before diving into the coverage of LSA types, two more definitions are needed: ■ Transit network—A network over which two or more OSPF routers have become neighbors, so traffic can transit from one to the other. ■ Stub network—A subnet on which a router has not formed ..
Using an RSM in conjunction with a Catalyst 5000 can be a very effective combination for medium-sized networks with moderate Layer 3 bandwidth requirements. Although it is faster than most router-on-a-stick implementations, its speed is not enough for many larger campus backbone applications. Instead, it is the RSMs integration into the Catalyst 5000 architecture that makes it most appealing. Features such as ease of configuration, an intuitive interface, a wide range of supp..
The IEEE defines VLANs as a group of devices participating in the same Layer 2 domain. All devices that can communicate with each other without needing to communicate through a router (only use hubs/repeaters and bridges, real or virtual) share the broadcast domain. The Layer 2 internetworking devices move frames through the broadcast domain by examining the destination MAC address. Then, by comparing the destination address to a table, the device can determine how to forward..
Monitoring and Troubleshooting RSVP Support for Frame Relay
Example 22-4 shows the configuration commands needed to add on routers R1 and R2 for this purpose. Example 22-4. Using ip rsvp sender-host and ip rsvp reservation-host to Routers R1 and R2 ! Router R1 R1(config)# ip rsvp sender-host 20.0.0.2 10.0.0.1 udp 7000 7001 16 1 ! Router R2 R2(config)# ip rsvp reservation-host 20.0.0.2 10.0.0.1 UDP 7000 7001 FF LOAD 16 1 The ip rsvp sender-host command causes router R1 to simulate an IP RSVP sender-host located at 10.0.0.1, which ..
Verifying Adaptive Frame Relay Traffic Shaping for Interface Congestion
In Example 9-1, the frame-relay adaptive-shaping interface-congestion 10 map-class configuration command is configured under the Frame Relay map class named FRTS on R2. The map class FRTS is attached to switched DLCI 200 under interface serial3/1. The queue depth is chosen to be 10 packets. The show frame-relay pvc command can be used to verify that Adaptive Frame Relay Traffic Shaping for Interface Congestion is enabled for the DLCI. This is shown in Example 9-2. Example 9..
