Q

What is different between IPv6 routing table entries compared to IPv4 routing table entries?

IPv6 routing tables include local route entries which IPv4 routing tables do not.

By design IPv6 is classless so all routes are effectively level 1 ultimate routes.

The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.

IPv6 does not use static routes to populate the routing table as used in IPv4.

This network has two connections to the ISP, one via router C and one via router B. The serial link between router A and router C supports EIGRP and is the primary link to the Internet. If the primary link fails, the administrator needs a floating static route that avoids recursive route lookups and any potential next-hop issues caused by the multiaccess nature of the Ethernet segment with router B. What should the administrator configure?

Create a static route pointing to 10.1.1.1 with an AD of 95.

Create a fully specified static route pointing to Fa0/0 with an AD of 1.

Create a fully specified static route pointing to Fa0/0 with an AD of 95.

The Branch Router has an OSPF neighbor relationship with the HQ router over the 198.51.0.4/30 network. The 198.51.0.8/30 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/1/1 100 was issued on Branch and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?

Add the next hop neighbor address of 198.51.0.8.

Change the administrative distance to 1.

Change the destination network to 198.51.0.5.

Change the administrative distance to 120.
