The log seems OK.
Router2 routing table :
-----------------------
2001:db8:0:1::/64 dev eth0 proto kernel metric 256
2001:db8:0:3::/64 via fe80::[Router1] dev eth1 proto bird metric
1024
2001:db8:0:5::/64 dev eth1 proto kernel metric 256
fe80::/64 dev eth0 proto kernel metric 256
fe80::/64 dev eth1 proto kernel metric 256
default via 2001:db8:0:1::1 dev eth0 proto static metric 1
default via fe80::[Router1] dev eth1 proto bird metric 1024
I am guesting the routing table was invoked with command `ip -6 route`
and the metrics 256 and 1024 are here probably OK, common values.

Hi Olivier,
I failed to reproduce the metric 1024. Can you please send a log
file from Router2?

Hello all ^^
I'm puzzled with a really weird RIPng default gateway
propagation
problem.
I don't quite understand what's happening. Here is what
happens ...
Network topology :
PC1---Router1---Router2----InternetGateway---z
RIPng enabled on PC1, Router1, Router2
Router2 has a static IPv6 DG ( Default Gateway ) to
InternetGateway
Router1 has no static IPv6 DG, and no kernel{learn} directive.
Router2=Ubuntu14.04 LTS, Router1=raspbian Wheezy, bird = last
version, compiled from sources
link-local addresses replaces with symbolic names ( ie
[fe80::Router1] )
Something really strange seems to happen :
. Router2 gets this routing table :
default via InternetGateway dev eth0 proto static metric 1
default via [fe80::Router1] dev eth1 proto bird metric 1024
Did you try commented out the learn directive in protocol kernel?
Did the metric 1024 disappear?
But Router1 isn't announcing any IPv6 DefaultGateway, just
::/0
metric 16 ( ie it is poisoning the route ).
( I checked using Wireshark ).
Is there a bug that transforms a received "::/0 metric 16"
into a
"default via [fe80::Router1] dev eth1 proto bird metric 1024"
route
?
Probably not.

port 521;
interface "*" { mode multicast; ttl security on; };
honor neighbor;
authentication none;
import all;
export all;
}
-------------------------------------------------------------
I managed to solve the problem, by having Router2 drop
incomming
::/0 announcements :
---------------------------------------------------------
import filter { # This block filters ::/0 in
if net ~ [ ::/0 ] then
reject "ripng:rejected:DG";
else
accept "ripng:accepted:not-DG";
};
export all;
Do you use filter at rip or at kernel protocol?
---------------------------------------------------------
the problem is solved, yet it puzzles me.
This is really strange. Does anybody understand what is
happening
??
