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!

Trying To Route Between Multiple Offices

Asked by NRL71 in Network Routers, Network Switches & Hubs

Tags: Cisco, 2600 router & catalyst 2950 switch

Here is the scenario:

I have three locations.

Two of the locations have dual T-1s onsite that are point-to-point.  I have a router at each location and the routers talk to each other using Multilink PPP.  At one of these locations there is also a fiber connection to a building nearby.  So using the 2600 router I have at that location it is plugged into a catalyst 2950 switch.  That switch is plugged into the vendor's switch which has the direct fiber link to the other site.  Here is the issue:  When I am on the 2950 I can ping the other site via the fiber link with no issues.  However, I cannot ping the router which I have trunked to the fast ethernet port.  I need to have connectivity over this fiber link AND also ping the router plus the other remote site across the T-1s.  Here is the config for the 2950 switch:
!

no service pad
