Hi guys, I hope this is the right subreddit for a question like this, but I'm hoping you guys might be able to point my team in the right direction.
I am part of a college group for our final project. We all have some background in the IT field, but we have run into an issue with our setup.
The topology is 2 routers(Cisco 1841) connected to each, with 2 switches( HP2530-24G ), and 2 servers(Linux). There is also one regular switch connected to both routers so clients can access the redundant network. They are connected via ethernet to be redundant, so that regardless if one of each goes down, the client can still access a web page on the server.
What we have done so far is set up VRRP between the routers, DHCP is set up on both routers, and spanning tree is set up on the switches.
What is happening is that the redundancy seems to work perfectly if we start unplugging the ethernet cables. We have tried all 72 possibilities of connection and they all work. Unless we unplug the power from one of the routers. Then the client will receive a Microsoft default IP? instead of the DHCP network assigned one it needs.
Right now, we plan to look at IP Helper and fiddle with that, and if that doesn't work, take a look at moving the DHCP from the routers to the servers, and see if we have a different outcome from the clientside.
Can you guys provide any insight or point us in the right direction. We plan to meet again tomorrow morning. Thanks!
