Several types of LSAs exist. This section discusses the nine types of LSAs documented in Table 8-2. Table 8-2. Types of LSA Type LSA Functionality 1 Router Defines the state and cost of the link to the neighbor and IP prefix associated with the point-to-point link. 2 Network Defines the number of routers attached to the segment. It gives information about the subnet mask on that segment. 3..
Ensuring the ELANs Are Functional between the Source and the Destination
If you configure the ELANs correctly, you should be able to ping each of the interfaces for each MPS and NHS along the default path between the source and destination client. If not, you either configured the ELAN incorrectly, you have a Layer 3 issue such as a bad IP address, or you have some routing protocol issues. Examine your intra-ELAN connectivity first. See if you can ping the neighbor device(s) within the ELAN. If you can, ping the next device in the next ELAN, eith..
Configuring WRED for Frame Relay
This section demonstrates the configuration tasks required to enable WRED for Frame Relay. WRED can be configured at the interface level or within the policy-map to initiate the WRED drop mechanism on a per-class basis for CBWFQ or LLQ. Enabling WRED on an Interface To enable WRED on an interface, use the following commands, beginning in the global configuration mode: Step 1. Enter the interface configuration mode of the Frame Relay interface on which yo..
If you want to increase the number of VTY ports available on the router for remote access, create a reference to the additional lines in the configuration as follows: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z.Router1(config)#line vty 0 9Router1(config-line)#exitRouter1(config)#endRouter1# This command defines the characteristics for a range of VTY ports from 0 to 9. Since ports 0 to 4 exist by default, this has the effect of ..
Configuring FRF.5 Network Interworking
This section discusses the configuration tasks required to enable Frame Relay network interworking (FRF.5) on the Cisco router. The network, consisting of four routers and an ATM LS1010 switch, is depicted in Figure 8-15 and is used to illustrate the configuration examples in this section. Note that R2 and R3 belong to the supported Cisco platforms required for Frame Relay to ATM Interworking. Figure 8-15. Simple Network to Illustrate the Configuration Examples for FRF.5 R2..
