Router R1 has been configured with the redistribute ospf 1 route - map fred command under router eigrp 1. The route map named fred needs to be configured to match routes to d etermine which routes are redistributed into EIGRP.Which of the following answers lists an item that cannot be matched by route map fred?（）

A. Subnet number

B. Next - hop router IP address of the route

C. Whether the route is an E1 or E2 route

D. The ro ute‘s tag

E. The number of router hops between the router and the subnet

Refer to the exhibit. OSPF has been configured on all routers in the network. However, router R1 does not receive a default route to router R2 as in tended. Which configuration change would ensure that R1 would receive a default route from R2? （）

A. Add the area 1 stub command on routers R1.

B. Add the always keyword to the default - information originate configuration command on router R2.

C. Remov e the default information originate configuration command from router R2 and place it on router R1.

D. Add the ip route 5.0.0.0 255.255.255.0 0.0.0.0 command to router R2.

A. Router R1 will deny the 172.16.1.0/26 route while permitting the 172.16.1.64/27 route to be advertised.

B. Router R1 will advertise both rou tes.

C. Router R1 should be reconfigured with an ACL instead of an ip prefix - list command.

D. Router R1 will deny the 172.16.1.0/27 route while permitting the 172.16.1.0/26 route to be advertised.

Refer to the exhibit. All routers have Protocol Independent Multicast (PIM) enabled interfaces. On the basis of the configuration provided on routers R1 and R2, which router will take on the func tion of rendezvous point (RP) for the multicast network? （）

A. both routers R1 and R2

B. router R1

C. router R2

D. none of the routers since they are not configured with static RP

Refer to the exhibit. Routers R1 and R2 have established a neighbor relationship and are exchanging routing information. The network design requires that R1 r eceive routing updates from R2, but not advertise any routes to R2. Which configuration command sequence will successfully accomplish this task? （）

A. R1(config)# router eigrp 1 R1(config - router)# passive - interface serial 0

B. R1(config)# access - list 2 0 deny any R1(config)# router eigrp 1 R1(config - router)# distribute - list 20 out serial 0

C. R2(config)# access - list 20 permit any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 in serial 0

D. R1(config)# access - list 20 permit any R 1(config)# router eigrp 1 R1(config - router)# distribute - list 20 in serial 0

E. R2(config)# access - list 20 deny any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 out serial 0

F. R2(config)# router eigrp 1 R2(config - router)# passive - interface serial 0

A. The i su 10.1.0.0/23 route is a suppressed route.

B. The i su 10.1. 0.0/23 route is a summary route.

D. The R1 IS - IS router is an ASBR.

E. The R1 IS - IS router is an ABR that belongs to multiple IS - IS areas.

F. The R1 IS - IS router is performing route aggregation and is suppressing the more specific 10.1.0.0/23 prefix.

一台Cisc0路由器R1的第3模块第1端口通过DDN的E1专线与一台远程路由器R2的第4模块第2端口相连，在R1的端口上封装PPP协议。为R1和R2端口分配的IP地址分别为193．42．91．201/30和193．42．91．202/30。下列R2的端口配置，正确的是（ ）。
