# setting up host ipv6 with SLAAC

## SLAAC (/64 only)

all you need is your kernel to listen to RAs

    Accept Router Advertisements (default is 1)

    0 -- Do not accept Router Advertisements
    1 -- Accept Router Advertisements if forwarding is disabled
    2 -- Overrule forwarding behaviour. Accept Router Advertisements even if forwarding is enabled

and eventually enforce them on the front-facing interface when dealing with a router (that would possibly manage a delegated prefix on its internal interface, while receiving a SLAAC address on its external interface)

    nic=xenbr0
    nic=eth0

    echo 2 > /proc/sys/net/ipv6/conf/$nic/accept_ra

check

        ls -lF /proc/sys/net/ipv6/conf/*/accept_ra
        cat /proc/sys/net/ipv6/conf/*/accept_ra

        ls -lF /proc/sys/net/ipv6/conf/*/autoconf
        cat /proc/sys/net/ipv6/conf/*/autoconf
