I have a dual 3GHz Xeon machine with a 2.4.21 kernel and thousands (15k+) of ipip tunnel interfaces. These are being used to tunnel traffic from remote routers, over a private network, and handed off to a third party....quoted
Is it possible to speed up creation of the interfaces? Currently it takes around 24 hours. Is there are more efficient way to handle a very large number of IP-IP tunnels? Would upgrading to a 2.6 kernel be of use?
2.6 (and the associated 'ip' tool) does have some improvements for showing very large numbers of interfaces. I haven't tried more than a few thousand though... Ben -- Ben Greear [off-list ref] Candela Technologies Inc http://www.candelatech.com
