Found something strange today. Suppose I have eth2 with VLAN 2 (eth2.2) associated with it. I add a routing table that is associated with eth2.2 (table 76 in my case). Now, I run: ifconfig eth2 down ifconfig eth2 up All of the routes in routing table 76 are now gone! I can understand how it might be useful to remove the routes from the eth2 table (as is also done), but it seems pretty extreme to muck with the VLAN device's tables as well. [root@...forge-33-46 local]# ip route show table 76 27.1.1.0/24 via 27.1.1.2 dev eth2.2 default via 27.1.1.1 dev eth2.2 [root@...forge-33-46 local]# ifconfig eth2.2 eth2.2 Link encap:Ethernet HWaddr 00:03:2D:08:33:47 inet addr:27.1.1.2 Bcast:27.1.1.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) [root@...forge-33-46 local]# ifconfig eth2 down;ifconfig eth2 up [root@...forge-33-46 local]# ip route show table 76 -- Ben Greear <greearb@...delatech.com> Candela Technologies Inc http://www.candelatech.com - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
