Description: CISCO equipment runs EIGRP, and the network is added a new product from Huawei. For a smooth cutover of network, CISCO equipment is configured with EIGRP and OSPF simultaneously, and enable the same network segment in EIGRP and OSPF so that both routing protocols could learn the same route. The priority of EIGRP is higher than that of OSPF, so the configuration of OSPF will not influence the normal running of network. When the network runs well, change the priority of EIGRP, and CISCO equipment is switched to OSPF first; at this point, if no problem occurs, the configuration of EIGRP could be deleted then, without any impact on current network. However, problem occurs to network many times after CISCO equipment is configured with two routing protocols, and partial routes cannot be learned. Network crashes, and the network sentence in EIGRP is lost.
Network Fails Because of Abnormal Running of Equipment Arising from that CISCO R
