interview question..

hi,

in interview i have faced this question.

question: I have 200 servers they are connected to 20 layer2 access switches (each server connected to two switches for redundancy)

20 layer2 access switches are connected to 2 layer3 distribution switches. (each access switch connected to two distribution switches)

2 layer3 switches are connected to two routers, where each router is connected to one ISP.( each distribution switch connected to two routers)

If I want no single point of failure in the network, what are the protocols to be used on each device?

on servers?

on access switches?

on distribution switches?

on edge routers?

Regards

Re: interview question..

My answer would be:

On Servers) NIC Teaming configured for Failover

On Access Switches) RSTP

On Distribution switches) RSTP & HSRP for the Access Layer, EIGRP/OSPF toward the edge routers.

On Edge Routers) BGP to ISP, EIGRP/OSPF to Distribution switches.

Please remember to rate all helpful posts.

Regards,

Brad

Re: interview question..

IMHO, there are many possible solutions to this question. Here's my take on it.

On Servers - IOS Server Load Balancing

On Access Switches - Uplink Fast feature of STP

On Distribution Switches - HSRP

On Edge Routers - BGP

HTH,

Sundar
