[单选题] Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）

A、The no auto - summary command needs to be added under router eigrp 1 B、The subnets keyword was not included in the redistribute command under router ospf 1 C、The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router A D、The default - information originate command needs to be added under router ospf 1 E、The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF

[单选题] Router R1 currently has no configuration related to IPv6 or IPv4. The following configuration exis ts in a planning document intended to be used to copy/paste into Router R1 to enable EIGRP for IPv6 on interfaces F0/0 and S0/0/0. No other related configuration exists. Assuming F0/0 and S0/0/0 reach an up/up state, which of the following is true about EIGRP for IPv6 on R1 after this configuration has been pasted into R1?（） ipv6 router eigrp 1 ipv6 unicast- routing interface f0/0 ipv6 address 2000::1/64 ipv6 eigrp 1 interface s0/0/0 ipv6 address 2001::/64 eui - 64 ipv6 eigrp 1

A、EIGRP works on F0/0 and S0/0/0 without further configuration B、EIGRP works with the addition of one command: a no shutdown command in EIGRP router configuration modE C、EIGRP works with the addition of one command: an eigrp router - id command in EIGRP router configurat ion modE D、EIGRP for IPv6 needs at least two more configuration commands before it works on R1
