#20354: Statefull IPv6 adressing does not broadcast correct IPv6 gateway
-------------------------------------------------+-------------------------
Reporter: gnutella | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Chaos
Component: base system | Calmer (trunk)
Keywords: ipv6 dhcpv6 gateway ra_management | Version: Trunk
nexthop |
-------------------------------------------------+-------------------------
Using OpenWRT latest development build:
OpenWRT is configured to serve stateful IPv6 only:
{{{
config dhcp 'lan'
....
option ra 'server'
option dhcpv6 'server'
option ra_management '2'
config host
option name 'sony-vaio'
option ip '192.168.1.x'
option mac '54:42:49:xx:xx:xx'
option duid '0004901071a15f278795axxxxxxxxxxxxxxxxxxxxx'
option hostid '3'
}}}
/etc/config/networking
{{{
config globals 'globals'
option ula_prefix 'fe80:ea94:f6ff:febb::'
....
config interface 'lan'
option ifname 'eth0.1'
option force_link '1'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.x'
option netmask '255.255.255.0'
option proto 'static'
option ip6addr '2a01:e35:xxxx:xxx::1:fe/64'
option ip6prefix '2a01:e35:xxxx:xxxx::/64'
option ip6gw '2a01:e35:xxxx:xxxx::1'
option ip6assign '64'
}}}
The client is a Debian workstation with IPv6 support.
The client receives the correct IPv6:
2a01:e35:xxxx:xxxx::1
But the route is not set to IPv6 adress of the gateway within the
ula_prefix range. As a result, client cannot connect to IPv6.
Client routing address is;
{{{
/sbin/route -A inet6
Table de routage IPv6 du noyau
Destination Next Hop Flag Met Ref Use
If
2a01:e35:87d8:61b0::3/128 :: U 256 0 0
eth0
fe80::/64 :: U 256 0 7
eth0
::/0 :: !n -1 1286863
lo
::1/128 :: Un 0 11
135 lo
2a01:e35:87d8:61b0::3/128 :: Un 0 1 21

fe80::5642:49ff:fe87:4f74/128 :: Un 0 1 37
lo
ff00::/8 :: U 256 0 0
eth0
::/0 :: !n -1 1286863
lo
}}}
There is a missing entry:
{{{
::/0 fe80::ea94:f6ff:febb:ae16 UG 100 3 0
eth0
}}}
What is your opinion? Is this a bug or a feature which needs more
configuration? How can server a default IPv6 gateway to client, correctly
set to openWRT gateway ula_prefix + suffix?
