 +====== Autoconfig and RA ======
 +
 +[[http://strugglers.net/~andy/blog/2011/09/04/linux-ipv6-router-advertisements-and-forwarding/]]
 +
 +Auto configuration can be disabled temporary for eth1 with:
 +
 +<code bash>
 +sudo sysctl -w net.ipv6.conf.eth1.autoconf=0
 +sudo sysctl -w net.ipv6.conf.eth1.accept_ra=0
 +</code>
 +
 +or for all interfaces with:
 +
 +<code bash>
 +sudo sysctl -w net.ipv6.conf.all.autoconf=0
 +sudo sysctl -w net.ipv6.conf.all.accept_ra=0
 +</code>
 +
 +Reenabling works by using 1 instead of 0 in the call.

 +>**R**outer **ADV**ertisement **D**aemon. This daemon listens to router solicitations (RS)
 +>and answers with router advertisement (RA). Furthermore unsolicited RAs are also sent from time to time.
