set ip6 conn name name 6rd-tunnel ipv4-conn-oid ipv4_name
Sets the 6rd connection named name to tunnel over an associated IPv4 connection named ipv4_name .
set ip6 conn name name 6rd-tunnel use-dhcp-values [ off | on ]
If this parameter is on, 6rd-provisioned parameters are obtained via the underlying DHCPv4 client associated with
IPv4 connection named ipv4-name. See "draft-ietf-softwire-ipv6-6rd-10" for DHCP format description.
ip6 conn (type = rd, 6rd-tunnel use-dhcp-values = off).
set ip6 conn name name 6rd-tunnel prefix IPv6_address
6rd domain prefix.
set ip6 conn name name 6rd-tunnel prefix-length value [ 1 - 63 ]
6rd domain prefix length.
set ip6 conn name name 6rd-tunnel ipv4-common-bits value [ 0 - 31 ]
The number of bits common to all IPv4 addresses within the 6rd domain. The top-most bits of the IPv4 address
will be "subtracted" from the 6rd address. If the whole 32-bit IPv4 address is contained in the 6rd IPv6 address,
this value is set to zero. Default is 0, meaning all 42 bits of the IPv4 address are embedded in the 6rd prefix.
set ip6 conn name name 6rd-tunnel relay-ipv4-addr IPv4_address
The IPv4 anycast address of the 6rd border gateway.
set ip6 conn name name 6rd-tunnel ipv4-tx-tos-mode [ off | use-ipv6 ]
off means the TOS field in the IPv4 header is set to zero for transmitted 6rd packets. use-ipv6 means the the TOS
field in the IPv4 header is set to the DS field of the 6rd-encapsulated IPv6 packet.
set ip6 conn name name 6rd-tunnel ipv4-tx-to-br [ off | on ]
off means each packet set to a destination IPv6 address within the originating 6rd domain is sent directly to the
6rd endpoint. on means that all packets are transmitted to the 6rd border gateway.
AICCU (SixXS tunnel broker) Connections
ip6 conn (type = aiccu, side = wan).
This connection type enables an IPv6 connection to the IPv6 internet
over an IPv4/NAT/UDP tunnel to a tunnel endpoint administered by tunnel broker SIXXS (www.sixxs.net).
You set up an account with SIXXS, and subsequently get assigned a tunnel and a subnet (usually a /48 subnet).
set ip6 conn name name aiccu username username
SIXXS username.
set ip6 conn name name aiccu password password
SIXXS password.
