We have two networks that need connecting and having problems.
Network 1 is using subnet 192.168.1.0/24 on Vlan 1 and we need to add network 2 to network one on the same subnet 192.168.1.0/24, the problem is network 2 3750 switch on Vlan 1 is using 10.1.1.0 .
I created a new vlan on network 2 3750 switch called Vlan 242 with ip address 192.168.1.241 /24, we see the trunk come up and protocol is up. I’m not able to ping 192.168.1.1 from network 2 3750 switch.
After checking I see spanning tree is pruning the trunked port for vlan 242.
I’m trying to connect both networks on the same subnet 192.168.1.x I can’t change network 1 vlan 1 as other equipment is connected to that network, we can’t change network 2 3750 switch vlan 1 10.1.1.x as other equipment is connected to that network.
What’s required to make both networks talk on the same subnet without changing the whole network to make this work
Thank you
