VTP/ISL Issue - Spanning VLANs over two switches

[TALLCHRIS]

Hi All

We're trying to span multiple VLAN's over two Catalyst 3524's. We've used VTP to mirror the VLAN setup/database on both switches and connected the switches using an ISL Trunk. The VLAN's work but the problem arises when data travels over the ISL Trunk.

I require packets from VLAN1 on Switch A to be delivered to VLAN1 on Switch B, instead the traffic is currently able to leave VLAN1 Switch A and then travel to any VLAN on Switch B.

Any ideas ?

Thanks

To disable HSRP use commands

no standby group-no

also for the problem , I agree with you that the DL380 may act as a router , so all vlans can talk, we can test with only switches and trunks
