This information is needed to support IPv6 and the software download. There is a workaround in place since SLAAC is not currently supported. However, to take advantage of the workaround, the following custom DHCP options must be implemented.
In addition to the standard DHCP options required by the OIB for software download, the customer is required to create 2 custom DHCPv6 options and an optional third option if a IPv6 prefix length other than /64 is required for the OIB.
# Define custom options to provide IPv6 Default Route, Prefix and any Static Routes:
# this is a short-term work around until we are able to receive RA messages.
option dhcp6.default-route code 214 = array of ip6-address;
option dhcp6.static-routes code 216 = array of ip6-address;
# add if OIB Prefix Length is something other than the /64 default.
option dhcp6.prefix code 215 = unsigned integer 8;
dhcp6.default-route will be assigned two IPv6 address, order is important, the Gateway Router’s Link-Local IPv6 Address followed by it’s Global IPv6 Address.
dhcp6. static-routes will be assigned a list of IPv6 addresses of any servers the OIB needs to reach that are within the same prefix as the OIB.
option dhcp6.prefix is the prefix length the OIB would have been assigned by the Router Advertisement message.
SLACC is not supported at this time. The OIB’s Global IP Address must be assigned by the DHCPv6 Server.
