Hi,
Looking at the IPv6 route table on 14.07 rc-1 for the LAN interface, there
is a /60 rather than a /64 route out the interface. This means that 16 x
/64s are being routed out the LAN interface rather than a single one.
The RA Prefix Information Options in the RAs being sent out the router
correctly list single /64s for my global /56 prefix and the ULA prefix.
e.g., for the ULA prefix, the IPv6 route table entry:
root@OpenWrt:~# ip -6 route list | grep fd0f:f1b5:2af::
fd0f:f1b5:2af::/60 dev br-lan proto kernel metric 256
unreachable fd0f:f1b5:2af::/48 dev lo proto static metric 2147483647
error -128
root@OpenWrt:~#
The corresponding correct IPv6 Router Advertisement PIO (from rdisc6
output):
Prefix : fd0f:f1b5:2af::/64
Valid time : 7200 (0x00001c20) seconds
Pref. time : 1800 (0x00000708) seconds
