Hello, I have configured my ethernet device eth0 for jumbo frames: ifconfig eth0 mtu 9000 I have a vlan eth0.3 on 192.168.0.1 that needs this jumbo frame size. I also have an alias eth0:test on 192.168.1.1 that can not support jumbo frames, so I added a route: ip route change 192.168.1.0/24 dev eth0 src 192.168.1.1 mtu lock 1500 This works fine, on 192.168.0.1 packets go out with size 9000 and on 192.168.1.1 packets go out with 1500. Now I need a broadcast (of a large packet) to 192.168.1.255 but so far I wasn't able to force Linux to use the mtu size of 1500 for broadcast (kernel 2.6.29). I tried: ip route change table local broadcast 192.168.1.255 dev eth0 src 192.168.1.1 mtu lock 1500 without success. Any ideas?
