Router1 and Router2 are running EIGRP. All interfaces are operational and packets can be forwarded between all networks. What information will be found in the routing table for Router1?

• Router1 will have 6 directly connected networks.
• The administrative distance of the route to network 172.16.0.0 will be 90.
• The metric for routes to 172.16.0.0 will be 1.
• The interface that is used to forward packets to 172.16.0.0 will always be the S0/1 interface.

• The routers in the network are operating with dynamic routing protocols.
• The routers in the network are operating with compatible versions of IOS.
• The routers in the network are operating with the same routing tables.
• The routers in the network are operating with consistent routing knowledge.

Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2?

• R1 will install a RIP route using network A in its routing table because the administrative distance of RIP is higher than EIGRP.
• R1 will install a RIP route using network A in its routing table because the path cost from RIP is lower than EIGRP.
• R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is lower than RIP.
• R1 will install an EIGRP route using network B in its routing table because the path cost from EIGRP is lower than RIP.
• R1 will install an EIGRP route and a RIP route in its routing table and load balance between them.

• A packet destined for host 192.168.252.2 will be forwarded out the interface connected to network 209.165.201.0/24.
• The value, 120, is used to determine the best path when a router has more than one routing protocol configured for the same destination network.
• This route was manually configured using the ip route command.
• 192.168.252.2 is an interface on the router that produced this output.

• The cost for this link has a value of 129.
• The clock rate on this serial interface is set to 129,000.
• The next-hop router is 129 hops away from this router.
• This route has been updated 129 times in this routing table.

• sends subnet mask information in routing updates
• sends complete routing table update to all neighbors
• is supported by RIP version 1
• allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
• reduces the amount of address space available in an organization

• The administrative distance of this route is 1.
• 192.168.1.2 is the address of an interface on this router.
• This route will display as a directly connected network in the routing table.
• Packets with a destination IP address of 192.168.1.2 will be forwarded to the 10.0.0.0/24 network first.
