Which is the type of OSPF protocol
Interior gateway protocol
How OSPF is used
To distribute routing information within single AS
Which technology used by OSPF
Link state technology
Which new concept has been introduced in OSPF
- Authentication of routing updates
- Variable length Subnet Mask VLSM
- Route summarization
OSPF versus RIP
What is the maximum hop counts supported by RIP
15
Does RIP support VLSM
No
How RIP send updates
Periodic broadcast of full routing table
Consume a large amount of bandwidth
1) RIP converges _____ than OSPF
Which concept RIP does not support
Network delay and lick costs
How routing decision done by RIP
Based on hop counts
Which path is preferred in RIP?
Path with a lowest hop count to a destination
What is the drawback of selecting path based on hop count
Longer path having better bandwidth and less delay not
preferred
2) RIP networks are ___ networks
Does RIP network support areas or boundaries
No
Which enhancement were introduced in RIP version 2
VLSM , authentication and multicast routing updates
What are limitation with RIP version 2
Routing decision on hop counts
Slow convergence
Is there any limitation of hop count on OSPF network
No
How OSPF send link state updates
Using multicast address
When OSPF send updates
In case routing changes
Does OSPF routers send periodic updates?
no
3)OSPF has better ____ than RIP
How OSPF network is design
Logical divided into areas
Hierarchical design
What is the advantage of logically dividing network into areas
Limits link state updates
What are the various features of OSPF
- Routing authentication based on various method
- Provide better load balancing
- Transfer and tagging of external routes injected in to an Autonomous System
- Keep track of external routes injected by protocol like BGP
