What command injects a default route into an OSPF network?
CCNA Guide to Cisco Networking Fourth Edition Ch.8 Answer: OSPF is configured using the router ospf [process id] command.
Which internal routing protocol would use if you needed to route between Cisco and non-Cisco equipment?
Open standard protocols: Rip or OSPF. They are not Cisco proprietary protocols.
What are the three router roles in an OSPF network?
Designated router, the backup designated router, and the DROTHER Internetworking with Cisco and Microsoft Technologies pg. 306-307
What is topology database in ospf?
In OSPF, a topology database is a data structure that each router maintains to store information about the network topology within an OSPF area. It includes details such as the network links, their costs, and the routers connected to those links. This database is used to calculate the best routes for routing packets through the network.
What does DR and BDR stand for in Cisco IOS?
A DR and BDR in a Cisco network stands for Designated Router and Backup Designated Router. These designations are used when working with certain routing protocols such as Open-Shortest Path First (OSPF)
What factor does the Cisco implementation of OSPF use to pick the best route?
Bandwidth
Should EIGRP only be run on networks with Cisco equipment?
EIGRP is a Cisco proprietary routing protocol and therefore can only be used with Cisco routers.You can do route redistribution on Cisco routers, this allows you to take routes from another routing protocol (such as OSPF or RIP) and place them into the EIGRP network that way downstream nodes can be informed of routes available.
What is ospf throttle?
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
What is the metric that OSPF uses?
OSPF uses the path cost metric to determine the best route to a destination network. The path cost is based on the bandwidth of the link. Lower path costs indicate faster or more desirable paths.
What does the cost of an OSPF link indicate?
The cost of an OSPF (Open Shortest Path First) link indicates the metric used to determine the "expense" of using that link for routing traffic. It is typically based on the bandwidth of the link, with lower costs assigned to higher bandwidth connections, making them more favorable for routing paths. OSPF uses these costs to calculate the shortest path to a destination, allowing for efficient network traffic management. Essentially, the link cost helps the OSPF algorithm make optimal routing decisions.
Which command correctly starts routing process in cisco router?
To start the routing process on a Cisco router, you typically enter the command router [routing_protocol] in global configuration mode, where [routing_protocol] could be protocols like rip, ospf, or eigrp. For example, to start the OSPF routing process, you would use the command router ospf [process_id], where [process_id] is a unique identifier for the OSPF process. This command enables the routing protocol and allows for configuration of related settings.
How many types of LSAs does OSPF support?
5 types Internetworking with Cisco and Microsoft Technologies pg. 307
