I've been working through the configuration to provide MAP-T rules to a dhcpv6
population via the published option. I'm fairly new to Kea, so could use a bit
of help with both the options themselves and the config syntax. The DMR and
46-rule options are pretty straightforward, but the portmap rules aren't very
clean in the docs. I'm trying to implement the following:
DMR: 2001:yyyy:e3a7:1::0/64
V4 Prefix: 192.168.254.0/24
V4 bit length: 8
V6 Prefix: 2001:xxxx:30::/48
EA bit length: 14
PSID Length: 6
PSID Offset 6
The items I can't find a "home" for are the EA bit length, and PSID length and
offset. Also, how do you properly define the options such that the parser
doesn't complain when it hit the "space" stanzas (that's a simple newbie Kea
problem, hopefully)? All of the PDs for my CPEs are within the /48 listed and
the setup works properly if simply bypass the DHCP aspect and hard-code the WAN
and MAP values in the CPE (in this case, a virtual OpenWRT ).
BTW, I know the V4 prefix in use is still RFC1918, but in the context of my
development space, it's the "public shared block".
Here's my example:
# DHCPv6 configuration starts here.
"Dhcp6":
{
# Add names of interfaces to listen on.
"interfaces-config": {
"interfaces": [ "eth0" ]
},
"option-data": [
{
"name": "s46-cont-mapt",
},
{
"space": "s46-cont-mapt-options",
"name": "s46-rule",
"data": "128, 14, 24, 192.168.254.0, 2001:xxxx:30::/48"
},
{
"space": "s46-cont-mapt-options",
"name": "s46-dmr",
"data": "2001:yyyy:e3a7:1::0/64"
},
{
"space": "s46-rule-options",
"name": "s46-portparams",
"data": "2, 3/4"
}
Thanks.
