R1(config)# ipv6 route 2001:db8:32::/64 G0/0 R1(config)# ipv6 route ::/0 G0/0 fe80::2 R1(config)# ipv6 route ::/0 G0/1 fe80::2* R1(config)# ipv6 route 2001:db8:32::/64 G0/1 fe80::2 To route packets to unknown IPv6 networks a router will need an IPv6 default route. The static route ipv6 route ::/0 G0/1 fe80::2 will match all networks and send packets out the specified exit interface G0/1 toward R2. 7. Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 Which route would have to go down in order for this static route to appear in the routing table? a default route a static route to the 192.168.10.0/24 network* an OSPF-learned route to the 192.168.10.0/24 network an EIGRP-learned route to the 192.168.10.0/24 network The administrative distance of 5 added to the end of the static route creates a floating static situation for a static route that goes down. Static routes have a default administrative distance of 1. This route that has an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168.10.0/24 goes down or was never entered. The administrative distance of 5 added to the end of the static route configuration creates a floating static route that will be placed in the routing table when the primary route to the same destination network goes down. By default, a static route to the 192.168.10.0/24 network has an administrative distance of 1. Therefore, the floating route with an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168.10.0/24 goes down or was never entered. Because the floating route has an administrative distance of 5, the route is preferred to an OSPF-learned route (with the administrative distance of 110) or an EIGRP-learned route (with the administrative distance of 110) to the same destination network.

8. Refer to the exhibit. The routing table for R2 is as follows: Gateway of last resort is not set 10.0.0.0/30 is subnetted, 2 subnets C 10.0.0.0 is directly connected, Serial0/0/0 C 10.0.0.4 is directly connected, Serial0/0/1 192.168.10.0/26 is subnetted, 3 subnets S 192.168.10.0 is directly connected, Serial0/0/0 C 192.168.10.64 is directly connected, FastEthernet0/0 S 192.168.10.128 [1/0] via 10.0.0.6 What will router R2 do with a packet destined for 192.168.10.129? drop the packet send the packet out interface Serial0/0/0 send the packet out interface Serial0/0/1* send the packet out interface FastEthernet0/0 When a static route is configured with the next hop address (as in the case of the 192.168.10.128 network), the output of the show ip route command lists the route as “via” a particular IP address. The router has to look up that IP address to determine which interface to send the packet out. Because the IP address of 10.0.0.6 is part of network 10.0.0.4, the router sends the packet out interface Serial0/0/1.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
