Can MVRP cause loops?
When configuring MVRP and VSTP on an switched ring topology I noticed that the MVRP learned VLANs do not seem to learn spanningtree bridges. For example, with a topology of switch A - B - C - A, if...

It does appear that you've successfully configured vlans 203, 204, 209, and 215 to trunk out ge-0/0/47. When you say you cannot get an IP addresse for vlans 209 and 215 do you mean the devices plugged...

I mean the devices plugged into ports ge-0/0/0 and 0/0/3. The devices plugged into ports ge-0/0/1 and 0/0/4 pick up an ip address correctly and can access the network.

On the EX4300 when you enable any Security feature, like IP-Source Guard, the switch automatically enabled Dynamic Arp Inspection (DAI), which is a requirment for IP-SG to work. Go to:...

Thanks for the reply. I had looked at that guide but I don't see where it says specifically that you must set arp-inspection on at the same time with ip-source-guard. I see where you said " On the...

Yes Juniper is different. In older EX products, non-ELS, you needed to enable DAI first in order to get IP-SG to function. In new EX, like EX4300 with ELS (different chip set) when you enable DHCP...

Also seems that only phones don't want to work with this. Are there known issues? Can't run this feature on phone vlans? It works with computer on phone vlan, computer behind a phone, but not a phone...

I sound have added that, the dhcp-security binding is created initially, but the attempt to renew/rebind looks like it never is never acknoweleged by the switch.

TAC is your best bet now. What is your TAC case #? Is your config in the case?

Parts of it are in there, frankly you've been more helpful that tac case number is: 2017-0407-0587

Are you trunking the same vlans (203, 204, 209, and 215) on the Dell core switch interface connected to ge-0/1/0? It appears the issue is somewhere downstream, as your 2200 seems to be configured...
