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!

Catalyst 6513 Routing problems

Asked by u-boot96 in Network Operations, Network Routers, Network Design & Methodology

Tags: , , , , , ,

Hi, i have routing problems with vlan1 secondary addresses.
The facts :
we have a 6513 and i want to set it as our company default gateway.
We actually have 4 subnets (10.72.128.0/24;156.0/24;158.0/24;181.0/24).
I set our 6513 Vlan1 primary address to 10.72.128.254, and i set also 3 secondary IP for the vlan1, each for every network that we are using(10.72.158.254;156.254;181.254).
We have also a VPN on hyperway/mpls circuit, so we have two cisco 1841 in load balancing that give us a virtual IP that is our default gateway for the hiperway/mpls vpn and internet gate.  The two 1841 are our provider (Telecom Italia) property, so we can't do nothing without ask him to do for us. The provider IP gateway is 10.72.128.200 and so on for all our subnets (10.72.158.200;156.200;181.200), and the Telecom Italia routers are directly connected on our 6513.
I set as 6513 default gateway the 10.72.128.200 (the primary ip of our provider routers).
THE PROBLEMS :
When i set as default gateway in a test pc the 6513 Vlan1 primary address (10.72.128.254) the test PC work perfectly, it can browse internet, it can reach every remote point on the mpls vlan and also local lan browsing work perfectly. But if i try the same to a test pc in another network, for instance the 10.72.158.0/24 and i use as gw the 6513 vlan1 secondary IP, 10.72.158.254, the test pc seems to be isolated, i can reach only hosts that are on the same network, no internet browsing no vpn reacheable. If i do a trace of any ip not reacheable i have answer of time out  from the gateway (the 6513 vlan1 secondary address on the same network). It seems routing wtih Telecom Italia routers  is working only on the primary vlan1 network, and not with the other networks. Maybe because i set ad 6513 default gateway the Telecom Italia IP 10.72.128.200, but i don't know how add secondary gateway on the 6513, maybe i need only to specify a default gateway for each secondary network?
In the 6513 i have also a static route like that : 0.0.0.0 0.0.0.0 10.72.128.200 (the telecom italia IP router) i tried also to add more static route for each telecom italia IP addresses (0.0.0.0 0.0.0.0 10.72.158.254 etc. etc.) but the only thing that i obtained its something like a load balancing, sometime tracing an address i ha answer from an IP sometimes from another (i mean the ip on the static route).
I hope that someone can understand what i'm trying to explain and that someone can help me to solve this thing. I want to use our 6513 as default gateway for all our networks because i'll be able to do more networks or manage more vlans without ask things to our provider...except if i'll want to permit to new vlan to reach mpls for instance.
Thank you in advance.
