  • 第3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
