I don't use the same IPs, looking at: > ifconfig eth0.201 10.201.1.50 netmask 255.255.255.0 broadcast 10.201.1.255 > ifconfig eth0.202 10.202.1.50 netmask 255.255.255.0 broadcast 10.202.1.255 Please answer me the following questions: Is it wrong to set the IPs with the 'ifconfig' command? How can I set the broadcast with 'ip' command? And why, does Linux-vrf not work? Is there another known bug? Thanks and Regards Matthias Reply to: There is a known bug with the route cache, as a simple test case try using different IPs on the VRFs. If that works and your 'same IP' still doesn't work, then I think this is due to the route cache bug, and I will try to find time to investigate it. BTW the 'route' and 'ifconfig' utilities are not 'VRF' aware. You will want to use the 'ip' utility to check the status of VRF related configurations.
