set ip6 conn name name 6rd-tunnel type [ cpe | gateway ]
The 6rd connection can operate in “cpe” or “gateway” mode as configured by the type parameter. “cpe” mode
is used when operating as a CPE; “gateway” mode is used when operating as a “6rd relay” as per RFC 5569.
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 [ 1 - 63 ]
6rd domain prefix length.
set ip6 conn name name 6rd-tunnel ipv4-common-bits [ 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 force-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.
set ip6 conn name name 6rd-tunnel anti-spoof-enable [ off | on ]
Enables 6rd tunnel anti-spoofing. The default is off .
set ip6 conn name name 6rd-tunnel tx-df-bit-set [ off | on ]
Enables 6rd tunnel to set the Dont Fragment bit in the IPv4 header when transmitting. The default is off .
