The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

I need some network design guidance on configuring my Cisco infrastructure for redundancy using HSRP and ASA Active/Standby Failover.

Asked by Crossroads305 in Network Design & Methodology, Network Routers, Networking Hardware Firewalls

Tags: Cisco Routers, Firewalls, Switches, Redudancy, HSRP, Active/Failover

My network is represented in the attached diagram.  The left side is how the network currently looks.  The right side is the equipment I am going to add to make this network more redundant incase of hardware failure.   At the moment there will be only one ISP connection thats why you only see one Cisco 3640, but everything below that, I want to make redundant.  I'm not sure where to use HSRP and where to use static routes with different metrics.  I know for the ASA's I will have an Active/Standy failover configuration.  The 2821 routers handle all my site-to-site VPN's so I'm thinking I would run HSRP between those?  I'm not to sure the best way to make the switches redundant.  Right now all my different subnet switches come off the Cisco 3550 core switch.  I was thinking about adding a second ip route to the subnet switches telling traffic to go to the second core switch if the first one fails.  Just want some advice on what someone else thinks on this network design.  Thanks.
