NT2640 Cisco IOS Admin Distances & Juniper JUNOS Route Preferences Introduction Most routing protocols have metric structures and algorithms that are not compatible with other protocols. In a network with multiple routing protocols, the exchange of route information and the capability to select the best path across the multiple protocols are critical. Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the

summarized to allow for expansion to allow for additional hosts. I also chose to use the Open Shortest Path First protocol (OSPF) for the routing protocol. I initially wanted to use the Enhanced Interior Gateway Routing Protocol (EIGRP), but I personally didn’t want to use EIGRP

Scenario 1: End user complains of lack of connectivity to any resource not on the directly connected network. The host cannot ping its default gateway. The output of the “ipconfig /all” command is below. Also the IP address assigned to the router for that segment is also displayed below.

Labs 4B Lab 8.4 1.What extra parameters are necessary in the network command when using OSPF, as compared with RIP, RIPv2, and EIGRP? Router(config)#router ospf process-number 2. What is the purpose of areas in OSPF? An area defines the confines within which LSAs are contained. 3. What is the purpose of the DR? On broadcast, multiaccess networks, OSPF elects a DR, which acts as a central point for LSAs. On multiaccess networks such as Ethernet, OSPF routers elect a DR and establish
