Bug#861115: Please consider increasing net.ipv6.route.max_size default value

Severity: wishlist

Dear kernel maintainers,

By default, net.ipv6.route.max_size is set to 4096. Unfortunately, when doing
ipv6 routing, these days, this value is too low to hold all the internet
IPv6 routes. If you do ipv6 routing with quagga, it simply doesn't fit. As
much as I can tell, using 40 960 for this value in /etc/sysctl.conf made it
work for me. It's ok for me because I understood it, however, it is not
obvious at all for a newbie connecting for example to a Hurican Electric bgp
tunnel: it just looks like the routing is broken is needs a restart.

Your thoughts?

Cheers,

Thomas Goirand (zigo)
