But when I try to get a dchp address it fails because it doesn't know how to get to the 112 network so it has to be a routing issue on the switch right? I just can't for the life me figure out how to fix it.

So, make sure that the gateway IP set in the DHCP scope is in the 108 network instead of the 112.<BR /> <BR /> Thanks<BR /> Brad<BR /> Fri, 07 Sep 2018 19:15:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/vlan-configuration-issues/m-p/26800#M3690 BradP 2018-09-07T19:15:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/vlan-configuration-issues/m-p/26801#M3691 Sorry, I just realized I mistyped in the previous response. The gateway I gave it was 108.1, not 107.1. And the gateway in the dhcp offer is the 108.1 gateway.

The 112.251 gateway is the router, which is the router 108.1 is on, i.e. 108.1 is on port 16, 112.251 is on port 15. When there is no vlan involved and I gave my self a static 108 address, i could ping 112.18 just fine. What is about the vlan that all the sudden made it so that it didn't know where 108.0/24 is any more?<BR /> <BR /> Fri, 07 Sep 2018 19:15:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/vlan-configuration-issues/m-p/26805#M3695 Jaren_Boone 2018-09-07T19:15:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/vlan-configuration-issues/m-p/26806#M3696 OK that is why a network diagram is helpful.<BR /> <BR /> In that case configure bootrelay on the router and not on the switch.<BR /> <BR /> If the router has a interface/IP in all VLANs then I'd remove all the ipforwarding because the router should do the routing between the LANs and not the switch.<BR /> <BR /> Just give the switch one IP in whatever VLAN you use as a mgmt VLAN for remote access.
