OpenWRT routers: Difference between revisions

m (Not really a *better* way)
(Fixed!)
We need a way for the WAN to tell the LAN about the wider routing block, whilst letting the LAN only use for itself the first /64 block.
 
This turns out to be remarkably easy. On the AAISP control panel, add a /60 block of IPv6 addresses. When DHCPv6 requests prefix delegation, AAISP returns the lowest number address block - if this is the new /60 then that's what you'll get, otherwise you might have to unroute some or more of the /64 blocks.
I'm investigating the options:
 
In my case I see for ''wan_6'':
* Configure IPv6 on the WAN manually, not using DHCPv6
Protocol: Virtual dynamic interface (DHCPv6 client)
Uptime: 0h 40m 58s
IPv6: 2001:8b0:1111:1111:0:ffff:abcd:pqrs/128
IPv6-PD: 2001:8b0:xyz:4520::/60
 
And for ''lan'':
* Configure automatically with DHCPv6, and then add the missing route(s)
IPv6: 2001:8b0:9d7:4520:xxxx:xxxx:xxxx:xxxx/64
# ip -f inet6 route add default via fe80::203:97ff:feba:900 dev pppoe-wan
 
It's the ''ip6assign'' option in the config for the lan which determines that the lan uses a /64.
* See whether delegating a /60 is any better - does DHCPv6 PD reply with the /60 or just one /64 ?
