Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, and into the core of an Enterprise network. The branch also allows local hosts to communicate directly with public sites in th e Internet over this same DSL connection.Which of the following answers defines how the branch NAT config avoids performing NAT for the Enterprise directed traffic but does perform NAT for the Internet - directed traffic?（）

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?（）D 2000::/64 [90/1422516]via FE80::213:19FF:FE7B:5026, Serial0/0/1C 2000:0:0:1::/64 [0/0]via Serial0/0/1, directly connectedL 2000::1:213:19FF:FE7B:5004/128 [0/0]via Serial0/0/1, receive

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
