The following output occurs on Router R1 , which runs both EIGRP for IPv6 and OSPFv3, with redistribution from EIGRP into OSPF configured with the redistribute eigrp 1 metric 25 command. Interface S0/0/1 has been enabled for EIGRP ASN 1. Which of the following should be true of redistribution in  this case?（）

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 OSPFv3 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 OSPFv3 on R1 after this configuration has been pasted into R1?（） ipv6 router ospf 1 ipv6 unicast- routing interface f0 0 ipv6 address 2000 ::1 64 ipv6 ospf 1 area 1 interface s0 0 0 ipv6 address 2001:: 64 eui - 64 ipv6 ospf 1 area 0

A. OSPF works on F0/0 and S0/0/0 without further configuration
B. OSPF works with the addition of one command: a no shutdown command in OSPF router configur ation modE
C. OSPF works with the addition of one command: an router - id command in OSPF router configuration modE
D. OSPFv3 needs at least two more configuration commands before it works on R1

多项选择题Which of the following are true of both OSPFv2 and OSPFv3?（）

A. The method of choosing an OSPF router ID
B. Verification checks that must be validated before two routers can become OSPF neighbors
C. Support for route tags
D. Support for multiple instances per inter face

单项选择题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 R2s F0 0 interface. Which of the following is true about R1s route?（） interface f0 0 mac - address 1111.1111.1 111 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
