A network includes a RIPv2 domain, an EIGRP domain, and an OSPF domain. Each pair of routing domains has multiple routers redistributing routes between the p air of domains. The design requires that the redistribution configuration avoid matching based on prefix/length because of the trouble in maintaining such configurations.Which one of the following tools can be used in all three routing domains to attem pt to prevent domain loops?（）A. Setting route tagsB. Setting the default administrative distance differently for internal and external routesC. Setting administrative distance differently per routeD. Setting metrics much higher for all ext ernal routes than for all internal routes
考题

You have implemented mutual route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one o f the OSPF routers within the OSPF routing domain, you are seeing some, but not all of the expected routes. Which two things should you verify to troubleshoot this problem?（）A、The border router is using a proper seed metric for OSPFB、The border ro uter is using a proper seed metric for EIGRPC、The administrative distance is set for OSPF and EIGRPD、The missing EIGRP routes are present in the routing table of the border routerE、The subnet keyword on the border router in the redistribute EIG RP command
