第1题

[多选题] A company uses Routers R1 and R2 to connect to ISP1 and ISP2, respectively, with Routers I1 and I2 used at th e ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1. R1 and R2 do not share a common subnet, relying on other routers internal to the Enterprise for IP connectivity between the two routers. Which of the following could be used to prevent potential routing loops in this design?（）

A、Using an iBGP mesh inside the Enterprise core B、Configuring default routes in the Enterprise pointing to both R1 and R2 C、Redistributing BGP routes into the Enterprise IGP D、Tunneling the packets for the i BGP connection between R1 and R2

[单选题] Refer to the exhibit. Autonomous systems 200 and 300 have EBGP sessions established with their directly connected routers in au tonomous system 100. IGP has been configured on all routers in autonomous system 100 and they successfully exchange routing updates. Traffic originated in autonomous system 200 cannot reach the destination autonomous system 300. What configuration shoul d be done on the routers in autonomous system 100 in order for the traffic coming from autonomous system 200 to be forwarded to autonomous system 300?（）

A、IBGP session must be established between routers R1 R2 and R2 R3, and the synchronization must be turned off. B、IBGP speakers within autonomous 100 must be fully meshed, and the synchronization must be turned on. C、IBGP session must be established between routers R1 R2 and R2 R3, and the synchronization must be turned on. D、IBGP session mu st be established between routers R1 and R3, and the synchronization must be turned off. E、IBGP speakers within autonomous 100 must be fully meshed, and the synchronization must be turned off. F、IBGP session must be established between routers R1 and R3, and the synchronization must be turned on.

[多选题] Ten routers, R1 through R10, connect in a partial mesh over Frame Relay. For the mesh, R1 and R2 have PVCs connected to all other routers, but Routers R3 through R10 act as branch routers, with only two PVCs - one to R1 and one to R2. The routers u se IP subnet 10.1.1.0/24, with addresses 10.1.1.1, 10.1.1.2, and so on, through 10.1.1.10, respectively. The routers all use Inverse ARP to learn Frame Relay mapping information. All routers use a multipoint subinterface with network type point - tomultip oint nonbroadcast. A co - worker's implementation plan lists lots of configuration commands related to this design. The design states that all hosts should be able to ping all other hosts. Which commands are required for proper functioning of OSPF in this case?（）

A、frame - relay map commands on R3 - R10 referencing the other routers in this group B、Nine OSPF neighbor commands on each router C、Nine OSPF neighbor commands on R1 and R2, with only two such commands on R3 - R10 D、R1 and R2 with ip ospf prio rity 1 commands to ensure they become DR and BDR E、R3 - R10 with ip ospf priority 0 commands to ensure they do not become DR or BDR
