We have 3 2900 switches (L2) and 2 3550 (L3) switches. Configured on all of them are 15 vlans. To pass DHCP from a single server we have put IP addresses on the vlans. config looks as such
Switch1>vlan1 ip address 192.168.1.1
Switch2>vlan1 ip address 192.168.1.1
Switch3>vlan1 ip address 192.168.1.1
Switch4>vlan1 ip address 192.168.1.1
Switch5>vlan1 ip address 192.168.1.1
Switch6>vlan1 ip address 192.168.1.1
You get the idea....
So you can see that in each net there is excessive ARP brodcasts from the duplicate IPs. In the past we set VTP MODE to transparent and the broadcasts stopped. Unfortunately they are back again and im not sure what the deal is. Ive disabled and re-enabled the VTP commands and no dice. Ive left out alot of info but Im confident this is an easy fix. The layer 2 devices do not arp, just the 2 L3 ones fighting back and forth. Any help is much appreciated. THANKS!!!
