[*] Apply access-group 14 to interface FastEthernet 0/0． Add access-list 14 permit any any to the access list configuration． Configure the IP address of the FastEtherent 0/0 interface to 10．90．201．1． Add an interface description to the FastEthernet 0/0 interface configuration．

On point-to-point networks, OSPF hello packets are addressed to which address? 127．0．0．1 172．16．0．1 192．168．0．5 223．0．0．1 224．0．0．5

In order to allow the establishment of a Telnet session with a router, which set of commands must be configured? router(config)# line console 0 router(config-line)# enable password cisco router(config)# line console 0 router(config-line)# enable secret cisco router(config-line)# login router(config)# line console 0 router(config-line)# password cisco router(config-line)# login router(config)# line vty 0 router(config-line)# enable password cisco router(config)# line vty 0 router(config-line)# password cisco router(config-line)# login

Refer to the exhibit． The network shown in the exhibit is running the RIPv2 routing protocol． The network has converged, and the routers in this network are functioning properly． The FastEthernet0/0 interface on R1 goes down． In which two ways will the routers in this network respond to this change? [*] All routers will reference their topology database to determine if any backup routes to the 192．168．1．0 network are known． Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire． Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about connectivity to the 192．168．1．0 network． When router R2 learns from R1 that the link to the 192．168．1．0 network has been lost, R2 will respond by sending a route back to R1 with an infinite metric to the 192．168．1．0 network． R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic updates at an increased rate until the network again converges．
