IOS XR Basic EIGRPv6 Configuration On PE: Example
The following example shows how to configure EIGRP with a policy that filters incoming routes. This is a typical configuration for a router that has just one neighbor, but advertises other connected subnets. router eigrp 100 vrf ABC address-family ipv6 router-id 10.10.9.4 log-neighbor-changes log-neighbor-warnings &nbs..
Enhanced IGRP and Distribute-List
A distribution list is used to block routing information from being sent or received. This list can be applied on a per-routing protocol basis or a per-interface basis. When applied on a per-routing protocol basis, the distribution list will block all routing updates that are exiting or entering the protocol that do not pass the access-list. For example, consider this code: router eigrp 1 network 10.0.0.0 distribute-list 1 in access-list 1 deny 10.10.10.0 0.0.0.255 a..
Configuring Frame Relay Proprietary Payload Compression
The Cisco packet-by-packet payload compression can be configured on Frame Relay physical interface or on Frame Relay logical point-to-point or multipoint subinterfaces. This proprietary scheme uses the Stacker algorithm to predict the next character in a frame on a packet-by-packet basis. Hence, the dictionary is not conserved across packet boundaries. A single dictionary is used for all packets compressed on a line. This results in a lower compression ratio compared with the..
Using the area x range configuration command on your ABRs allows you summarize routes between OSPF areas: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#router ospf 55 Router1(config-router)#area 100 range 172.20.0.0 255.255.0.0 Router1(config-router)#area 0 range 172.25.0.0 255.255.0.0 Router1(config-router)#area 2 range 10.0.0.0 255.0.0.0 Router1(config-router)#exit Router1(config)#end Router1# The easiest way..
Troubleshooting Frame Relay Connections with Cisco IOS debug Commands
This final section discusses the common issues and problems encountered on Frame Relay networks and how several IOS debug commands are used for troubleshooting Frame Relay connections. In general, debug commands are used on a Cisco router only for diagnostic and troubleshooting purposes. During normal operation, all debug commands should be turned off. Debug commands generate massive overhead by taking up CPU cycles on the router. Enabling many debug commands at once can ove..
