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 f0/0mac - address 1111.1111.1 111ipv6 address 2000::/64 eui - 64ipv6 address 2001::1/64
