+====== Autoconfig and RA ======

+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.
+====== RADVD ======
+>**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.
+>This protocol is meant for host auto-configuration and not for route propagation between routers.
