Hi, I was trying to implement VRRP on linux IP. I have applied a kernel patch to alter the real mac address with the virtual mac address when a host requests for arp resolve for VRIP. But the problem I encountered is, a data packet with this faked mac is getting dropped by kernel. Is there any way to make a kernel to accept a packet with virtual mac? Thanks in advance Regards Muneer CH On Wed, 19 Oct 2005 Don Provan wrote : >Hope the list doesn't mind this Linux specific conversation.... > > > We are planning to run VRRP over a Logical Interface > > created in Linux > > IP.(similar to eth0) > >I'm not sure what this means.
