Hello,
I'm restoring this topic I've found on "quagga-users 14807".
Regarding IPv6 ...
Our setup is using two quagga routers.
The routers run OSPF6d for internal routing
They have a iBGP session between them and each has a eBGP peering
(direct) with our provider.
The provider only announces the default route ::/0 to both routers for
high availability.
We mark the routes received in one router as localpref=201 and in the
other localpref=302
I can ping 2001:690:810:5::1 in the router configured to be the active
one (LP=302) but the route isn't placed in the routing table reporting
"inaccessible" (see show command).
Running:
Quagga 1.2.2-gentoo ().

Is this expected?
I'm receving the route in the outbound interface and the address is
acessible via ND/ping
Any soluting via reconfiguration or official software update (excluding
personal patch)
TIA.
