I am running DHCP on my 2621 with 2 Ethernet Interfaces. Is it possible to turn the DHCP portion off on a particular interface, as it is trying to hand out addresses on the wrong subnet.
 
Yeah, add a deny statement to an extended access-list denying port 67, 68, and 546

67 - BootP Server
68 - BootP Client
546 if you are running IPv6

assign it to the interface inbound and outbound you don't want requests showing up on.

The other solution is to separate the subnets by another router. This will keep the MAC Layer Broadcasts from reaching the wrong interface.

No Ip helper statements, that would defeat the purpose of separating the subnets broadcast capabilities




 
Thanks for the idea.

 
They shouldn't be showing up unless you have the same ethernet port somehow tied to both networks.
