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.

BGP route distrobution question?

Asked by stamperb in Network Routers, Network Operations

Tags: bgp

I currently have a couple sites that connect to an MPLS that uses BGP.   I'm trying to figure out how the MPLS provider is getting my routes from Location 1, 2, and 3 to the other locations.  Right now all of my locations have this setup for BGP:  So the router bgp 65531 is the same at all of my locations.  The remote-as is always the same and the only change is the IP for the neighbor.

router bgp 65531
 no synchronization
 bgp log-neighbor-changes
 redistribute connected
 redistribute static
 neighbor 10.101.0.50 remote-as 13576
 neighbor 10.101.0.50 soft-reconfiguration inbound
 no auto-summary

So if Location 1 is 192.168.1.0/24 and location 2 is 192.168.2.0/24 and location 3 is 192.168.3.0/24 how are these routes getting into the tables of the other locations.  If I add a subinterface to my router at location 1 of 192.168.100.0/24 it will show up in the routing table at location 2 and 3.  So on the router that this all connects to how are thing distributing these networks to my other locations?  I've got 3 routers in a lab here setup.  1 of them is acting as the MPLS and the other two are connected via serial links to it.  So the MPLS currently has:
router bgp 13576
 syncronization
 bgp log-neighbor-changes
 redistribute connected
 neighbor 10.101.0.49 remote-as 65531
 neighbor 10.101.0.54 remote-as 65531

So the Location 1 and 2 routers have the same output as I llisted up above here.  I for some reason figured the routes from location 1 and 2 would exchange but they are not.  They do however exchange and show up on the MPLS router..they just don't quite make it to the location routers?
