DLSW+

We have Router1(R1) FE1 interface is connected through VLAN 100 to Switch 1 , the switch port is configured with portfast and the BPDU guard. R2 is also connected to SW1. R1 FE2 interface is connected to the user VLAN. We configured DLSW+ on R1 and created bridge group 15 and we put interface FE2 into bridge group 15, once we did that SW1 saw BPDU coming from R1 FE1 and it went to disable mode. I din't understand why R1 bridged the PBDU between FE2 and FE2.. Any Idea ?

Re: DLSW+

You should definately be able to configure DLSW on just one interface/VLAN on a switch without it affecting any other VLAN. That is, after all, the function of VLANs.

If you want to send DLSW traffic to multiple VLANs, then each should use a different bridge group to avoid bridging between VLANs and all the bridge groups should be tied to DLSW.
