Hi everyone, Either there is a fundamental lack of understanding on my part, (highly likely) on MT Vlan-ing/routing, or I'm just having a bad day. I have spun up a CHR box with two VM Nics, one on (VMNetwork) ether1 for management on my local subnet 192.168.1.0/24 which has a dhcp client, use this for winbox mgmt, etc. The other is direct ethernet connection to an HP Procurve 2910al, port 25 for now. VM Nic ether2 (LAN NIC for want of a better term) with Static IP on CHR 10.10.20.200/24 Hoping this can be the management Vlan network. (10.10.20.0/244) This is where i start getting lost in nomenclature and it really starting to get the better of me. This "link" would be: Trunk in Cisco Trunk in MT (?) not sure Tagged in HP As i understand it, I've followed this guide. https://forum.mikrotik.com/viewtopic.php?t=143620 For now, I do understand the 2910 will do layer 3 routing, i have chosen to keep with no ip routing on the switch. The reason for now is that most IP services are on the router. Moving routing may be beneficial but the current goal would like to get my devices correctly administered on layer 2 and 3. My only signs of layer two life is a ping from the HP to the CHR ether2 10.10.20.200 is responsive, 10.10.20.1 is not. Also I cannot ping the Vlan IP on the HP (10.10.20.254/24) from the CHR either via the management vlan interface or ether2. At the moment the switch is administered over serial. Attached is the router and switch config for you enjoyment, please let me know where I've gone awry in your eyes and I will try and knock this over, then write up something for posterity. thanks Simon.
