- Take a closer look at routing redistribution
- redistribute ospf?We can get the routes into ospf just fine, but how will the firewall know to get to 10.1.0.0 network hanging off the backside of Router 2? Don't we need to redistribute ospf back into rip?Great QuestionThat is a great question! You could do mutual redistribution (redistribution rip...

- Network statements
- I was under the impression that the network statements in EIGRP didn't need any mask information, that they were the same as for RIP and IGRP ie #network 10.0.0.0. The article indicates that a wildcard mask is needed just like in OSPF

- Configure IT Quick: Configure EIGRP with IP and IPX on Cisco routers
- Learn how to configure EIGRPEIGRP is sometimes referred to as a hybrid routing protocol, but Cisco calls it an advanced distance vector routing protocol. Cisco makes this reference primarily due to the way EIGRP handles convergence. With EIGRP, convergence, the process in which all routers share and process the same...

- How Does Unequal Cost Path Load Balancing (Variance) Work in IGRP and EIGRP?
- In general, load balancing is the capability of a router to distribute traffic over all the router network ports that are the same distance from the destination address. Load balancing increases the utilization of network segments, and so increases effective network bandwidth. There are two types of load balancing: equal...
