Hello,
I run rtadvd on a router, which also run ospfd (on 6.3).
rtadvd runs with static config (noifprefix):
fremen# cat /etc/rtadvd.conf
em0:\
:rdnss="2a01:e35:8aea:ac42::10":\
:dnssl="geekwu.org":\
:addr0="2001:41d0:fe4b:ec21::":\
:addr1="2a01:0e35:8aea:ac41::":\
:noifprefix:
em1:\
:rdnss="2a01:e35:8aea:ac42::10":\
:dnssl="geekwu.org":\
:addr0="2a01:e35:8aea:ac42::":\
:addr1="2001:41d0:fe4b:ec42::":\
:noifprefix:
em5:\
:rdnss="2001:41d0:fe4b:ec42::10":\
:dnssl="geekwu.org":\
:addr0="2a01:e35:8aea:ac43::":\
:noifprefix:
em4:\
:rdnss="2001:41d0:fe4b:ec42::10":\
:dnssl="geekwu.org":\
:addr="2001:41d0:fe4b:ecff::":\
:noifprefix:
if an ospf neighbour start advertising a new network (in my case
2001:41d0:fe4b:ecf1::/64), a route is inserted in the kernel:
fremen# route -n show -inet6|grep ecf1
2001:41d0:fe4b:ecf1::/64 fe80::225:22ff:fe1e:bb7%em1 UG
0 594 - 32 em1
but rtadvd starts advertising it on the link with the said neighbour.
I get this from radvdump running on a Linux host on this link:
#

# based on Router Advertisement from fe80::8621:df60:6d70:8da

AdvRouterAddr off;
}; # End of prefix definition
prefix 2001:41d0:fe4b:ec42::/64
{
AdvValidLifetime 2592000;
AdvPreferredLifetime 604800;
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
}; # End of prefix definition
prefix 2001:41d0:fe4b:ecf1::/64
{
AdvValidLifetime 2592000;
AdvPreferredLifetime 604800;
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
}; # End of prefix definition
RDNSS 2a01:e35:8aea:ac42::10
{
AdvRDNSSLifetime 900;
}; # End of RDNSS definition
DNSSL geekwu.org
{
AdvDNSSLLifetime 900;
}; # End of DNSSL definition
}; # End of interface definition
Why does rtadvd start advertising this prefix ?
If I withdraw the prefix from ospf, rtadvd stops advertising it.
Thanks,
Bastien
