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.

1 ethernet port, multiple virtual interfaces, multiple DHCP servers. How to set up?

Asked by Neo-Rio in Unix Networking, Tivoli Storage Manager

Tags: different

I have a laptop running FreeBSD 4.10 which has one ethernet port (fxp0)

I have so far configured the ethernet port and kernel to support three vlan virtual interfaces with static IPs. (vlan0, vlan1, vlan2). So far, I have got this working.

What I want to do now is make each of my vlan interfaces connect to a DHCP server to get their own IP adresses on different networks, but here's the catch: each vlan interface needs to connect to a different DHCP server.

I figure that since there's only one default gateway on the machine, all DHCP requests are going to end up at one DHCP server, therefore making all 3 virtual vlan interfaces get an IP from the same network. I don't want this to happen.

I know that in FreeBSD, rc.conf can be edited so that an interface gets its IP from DHCP (for example, ifconfig_fxp0="DHCP"

Is there any way I can set up rc.conf to get each virtual interface to point to a different DHCP server? If not, is there some set of commands I can use to do this?

Thanks
