Part II- Quick Interview questions on Routing
As per my earlier article on Quick interview question on Networking and Switching, Now I am coming up with the Quick interview question on Routing.
Lets have a Quick Interview questions on Routing now
Basics
- What is Router and Routing ?
- What is the difference between router and switch ?
- What is the difference between the static and dynamic routing protocols ?
- What is the difference between distance vector and Link state routing protocols ?
- What is the AD value of RIP, EIGRP, OSPF and BGP ?
- How we can define the static routing in the network ?

Dynamic Protocols- Internal Routing Protocols
- What is the difference between RIPv1, RIPv2 and RIPv3 ?
- How route is calculated in EIGRP protocol ?
- What is the EIGRP Stuck in Active state and how it can be resolved ?
- What is EIGRP passive interface ?
- What is EIGRP stub routing feature ?
- What are the different route types in EIGRP ?

- What are the different types of areas and the routers used in OSPF ?
- What are the different types of route in OSPF ?
- Why are loopbacks /32 is advertised in OSPF ?
- What is the purpose of variable IP-OSPF-Transmit-Delay ?
- What is the difference between ABR and ASBR routers in OSPF ?
- How many LSA's are there in the OSPF with full description?
- How DR/BDR select in the OSPF area ?
- What is the use of the P-bit in the OSPF ?
- How we can configure the OSPF on the router ?
- How we redistribute in the OSPF ?
Exterior Gateway Routing Protocol
- What is the AD value of BGP ?
- Port number of BGP ?
- Attributes of BGP ?

- How we can use Route reflection and what is the cluster and originate ID ?
- What is BGP peer group and why we are using it ?
- What are the various regular expression we are using in the BGP and what is the purpose of these ?
- What are various BGP community attributes and what is the purpose of that communities ?
- What is route-map, Prefix-List and filter-list in BGP, How we are using these for inbound and outbound traffic in BGP ?
- What is the difference between Local-Preference and AS-Path ?
- What is AS-prepand, AS-override and Local-AS features ?
