You are discovering that there are differences between the configuration of EIGRP for IPv6 and EIGRP for
IPv4. Which statement is true with regard to the difference?

A.
A router ID is required for both versions

B.
A router ID must be configured under the routing process for EIGRP for IPv4

C.
AS numbers are not required in EIGRP for IPv6

D.
AS numbers are not required in EIGRP for IPv4

Explanation:
Both versions of EIGRP require a router ID. The difference is that with EIGRP for IPv6, you must configure a
router ID under the routing process if there are no IPv4 addresses on the router. In EIGRP for IPv4, the router
can select one of the configured IPv4 addresses as the router ID.
A router ID can be configured under the routing process for EIGRP for IPv4, but it is not required. In EIGRP for
IPv4, the router can select one of the configured Pv4 addresses as the router ID.
AS numbers are required in both versions of EIGRP.
