    Set appropriate default for vxlan multicast ttl

    Currently no default is set which means vlxan multicast traffic
    is dropped at the first L3 router. This patch increases the default
    to 32 which is sufficient for any reasonable network fabric and
    can be overridden if necessary.

    Without this patch vxlan project networks on a routed underlay network
    are not functional
