Which Wide Area Network (WAN) switching technology is used by Asynchronous Transfer Mode (ATM)?
Which of the following is NOT a characteristic of Open Shortest Path First (OSPF)?
Is a Cisco-proprietary routing protocol
Has a default administrative distance of 110
Uses cost as the default metric
Which of the following statements describes split horizon?
The router learns from its neighbor that a route has gone down, and the router sends an update back to the neighbor with an infinite metric to that route. For a period of time, the router will ignore any route advertisements with a lower metric to a downed route.
A router will not send route information back out the same interface over which it was learned.
The moment a router determines a route has gone down, it will immediately send a route update with an infinite metric to that route.
The packets are flooded when a topology change occurs, causing network routers to update their topological databases and recalculate routes.
You would like for Router25 in your OSPF network to become the DR. You execute the show ip ospf interface command, receiving the output shown below. Router25# show ip ospf interface Ethernet0 is up, line protocol is up Internet Address 10.10.10.1/24, Area 0 Process ID 1,Router ID 10.10.10.1, Network Type BROADCAST, Cost: 10 Transmit Delay is 1 sec, State BDR, Priority 1 Designated Router (ID) 172.16.10.1, Interface address 10.10.10.2 Backup Designated router(ID)10.10.10.1,Interface address 10.10.10.1 You assign an IP address of 192.168.5.6 to the Ethernet1 interface of Router25 and enable the interface. However, Router25 does NOT become the designated router. What additional command must you execute to cause Router25 to become the DR?
Router25(config-router)# network 192.168.5.0 0.0.0.255 area 0
Router25(config-router)# network 192.168.5.0 0.0.0.255 area 1
Router25(config-router)# network 192.168.5.0 255.255.255.0 area 0
Router25(config)# network 192.168.5.0 0.0.0.255 area 0
