I got tasked with having to connect a netgear router into my network. The only way I can get the router to talk to my router is putting them on the same subnet.
Here is what my setup is like:
Cisco 29111 Router Trunk Port Cisco 3560 Access Port Netgear Router
10.110.141.254 /24 10.110.141.253 /24 192.168.23.1 /24
I created a vlan for the 3560 (vlan 333) for the Netgear Router to plugin. The only way I was able to talk to the Netgear router was to put a subinterface on my 2911 of 192.168.23.254. The third party has multiple networks in 192.168.X.X subnets. All /24 masks
Once I take this interface down I can't talk to the 192.168.23.1 router. Would it cause issues having both routers on the same subnet? I am using static routes on my side to route everything I need to the 192.168.23.1 router. The third party is also doing the same with static routes to get to my network.
I do not have administrative access to the Netgear and have never worked with them.
