Point-to-Point Configuration over NBMA
The point-to-point configuration requires an IP subnet for every link. This is the recommended way to run IS-IS over NBMA and the only way to do it on anything less than a full mesh. The configuration is simpler, because the link is point-to-point and there is no need to configure frame-relay map commands. As shown in Example 10-6, it is only necessary to create subinterfaces, configure those interfaces as point-to-point, start Frame Relay, and define the DLCI..
The NOTIFICATION Message and BGP Errors
Notification messages are sent in response to a BGP error condition. These include protocol errors such as malformed updates, confusion in the BGP state machine, or even unsupported options. After sending the NOTIFICATION, the sender closes the TCP connection and both peers invalidate any routes associated with the peering session. Each NOTIFICATION message contains a one-byte error code and a one-byte subcode, followed by variable-length, error-specific d..
RSVP-DiffServ integration provides a translation between RSVP and DiffServ technologies that is intended to leverage the strengths of each model. RSVP is used for bandwidth reservation at the edge of the network (where there are fewer flows and the most bandwidth constraints), but DiffServ is used over the backbone network so that the backbone routers do not have to keep per-flow states. This topology is shown in Figure 8-4. Figure 8-4. RSVP-DiffServ Integration [View full s..
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..
