[c-nsp] 3750 ip direct brioadcast

[Brian Turnbow]

Hello all, 
I have a couple of 3750s image on the boxes is 12.2(20)SE1 trunked back
on to the network all done with static routing. 
So I have int vlan 82 with an IP address and some ports set up as L3
ports with an IP address. 
All interfaces have ip direct broadcast disabled , and doing a show ip
int xxx I can see 
Directed broadcast forwarding is disabled
On all interfaces (even vlan interface) 
But the switch responds (from the vlan interface) to the FE ports
broadcast address.

So basically I have 
Int vlan 82 
Ip address 10.1.1.1 255.255.255.0 

And 
Int fast 1/0/1 
Ip address 192.168.0.1 255.255.255.0 


A ping gets sent to 192.168.1.255 , and the router responds from the
10.1.1.1 address with an echo reply. 

Anyone else seen this or have any ideas ?
