Router R1 connects to Router R2 over an Ethernet LAN with both routers using their F0/0 interfaces. R1 learns a route from R2 using EIGRP f or IPv6. That route lists F0/0 as the outgoing interface with R2 as the next hop. The configuration excerpt shows all relevant configuration on R2's F0/0 interface. Which of the following is true about R1's route?（）
interface f0/0
mac - address 1111.1111.1 111
ipv6 address 2000::/64 eui - 64
ipv6 address 2001::1/64

单项选择题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

单项选择题Router R1 currently has no configuration related to IPv6 or IPv4. The following configuration exists in a planning document, intended to be used to copy paste into Router R1 to enable RIPng and IPv6 on interfaces F0 0 and S0 0 0. No other related configuration exists. Which of the following is true about RIPng on R1 after this configuration has been pasted into R1?（） ipv6 unicast- routing interface f0 0 ipv6 rip one enable ipv6 address 2000::1 64 interface s0 0 0 ipv6 address 2001:: 64 eui - 64 ipv6 rip one enable

A. RIPng will be enabled on no interfaces.
B. RIPng will be enabled on one interface.
C. RIPng will  be enabled on two interfaces.
D. RIPng will advertise about prefixes connected to S0/0/0 and F0/0, but only send Updates on one interface.

多项选择题Which of the following features work the same in both RIP- 2 and RIPng?（）

A. Distance Vector Logi c
B. Uses UDP
C. Uses RIP - specific authentication
D. Maximum useful metric of 15
E. Automatic route summarization

单项选择题Router R1 lists the following output from a show command. Which of the following is true about R1?（） R1# show ip v6 interface f0 0 FastEthernet0 0 is up, line protocol is up IPv6 is enabled, link - local address is FE80::213:19FF:FE12:3456 No Virtual link - local address(es): Global unicast address(es): 2000::4:213:19FF:FE12:3456, subnet is 2000:0:0:4:: 64 [EUI] Jo ined group address(es): FF02::1 FF02::2 FF02::1:FF:12:3456

A. R1's solicited node multicast address is FF02::1:FF:12:3456.
B. R1's 2000::4:213:19FF:FE12:3456 address is a global unicast with all 128 bits statically configured.
C. Address FF02::2 is  R1's solicited node multicast.
D. R1's solicited node multicast, not listed in this output, would be FF02::213:19FF:FE12:3456.

多项选择题Router R1 has the following configuration. Assuming R1s F0 0 interface has a MAC address of 0200.0011.1111, what IPv6 addresses will R1 list for interface F0 0 in the output of the show ipv6 interface brief command?（） interface f0 0 ipv6 address 2345:0:0:8::1 64

A. 2345:0:0:8::1
B. 2345:0:0:8:0:FF:FE11:1111
C. FE80::8:0:FF:FE11:1111
