Explanation :
|
By default, IPv6 routing is not enabled on a router. To enable it, you issue the
ipv6 unicast-routing command in global configuration mode. As a best practice, you should also enter ipv6 cef in global configuration mode (not router configuration mode) to enable Cisco Express Forwarding for IPv6. However, ipv6 eigrp is not a valid command. |
interface f0/0 mac-address 1111.1111.1111 ipv6 address 2000::/64 eui-64 ipv6 address 2001::1/64
- A.The next hop is 2000::1311:11FF:FE11:1111
- B.The next hop is FE80::1311:11FF:FE11:1111
- C.The next hop is FE80::5111:11FF:FE11:1111
- D.The next hop is 2001::1

Explanation :
| EIGRP uses the link-local address as the next hop for routing protocols. Based on R2's MAC address, R2's link-local address on Fa 0/0 will be FE80::1311:11FF:FE11:1111. This value is derived by splitting the MAC, inserting FFFE, and flipping bit 7, making the initial hex 11 become hex 13. |
- A.Address-Family configuration mode
- B.Address-Family-Interface configuration mode
- C.Address-Family-Global configuration mode
- D.Address-Family-Topology configuration mode
- Answer & Explanation

Explanation :

General EIGRP commands (for example, metric , eigrp stub , and eigrp router-id ) are configured under address-family configuration mode. Commands entered under interface configuration mode with a traditional EIGRP configuration (for example, authentication , bandwidth-percent , hello-interval , holdtime , passive-interface , and split-horizon ) are entered under address-family-interface configuration mode with Named EIGRP. Commands having a direct impact on a router's EIGRP topology (for example, autosummary , maximum-paths , redistribute , and variance ) are given under addressfamily- topology configuration mode. There is no address-family-global configuration mode. |
- A.address-family global
- B.af-interface default
- C.af-interface-all
- D.address-family *

Explanation :
|
EIGRP parameters configured under interface configuration mode with a traditional EIGRP configuration can be configured under address-family-interface configuration mode with Named EIGRP. To enter address-family-interface configuration mode for a specific interface, you can enter the af-interface interface_identifier command. However, if you want an interface setting to be applied to all interfaces, you can enter the af-interface default command. Although commands entered from this configuration mode are inherited by all router interfaces, you can go into addressfamily- interface configuration mode for specific interfaces to override any globally configured interface settings. None of the commands given in the question, other than af-interface default , are valid. |
- A.show address-family ipv4 topology
- B.show ip eigrp topology
- C.show address-family-topology
- D.show ip address-family
- Answer & Explanation

Explanation :
| Even though Named EIGRP is configured quite differently than a traditional EIGRP configuration, the verification commands remain the same. Therefore, to view a router's EIGRP for IPv4 topology table, you would issue the same show ip eigrp topology command that you would use with a traditional EIGRP for IPv4 configuration. |
