Subject: fe80::/64 route missing on GRE tunnels
Date: Tue, 11 Feb 2014 22:55:11 +0100 [thread overview]
Message-ID: <20140211215510.GA6994@sesse.net> (raw)
Hi,
It seems that recent kernels no longer automatically add the link-local route
to GRE tunnels. 3.10.27 does it right:
root@morgental:~# ip tunnel add foo mode gre remote 1.2.3.4 ttl 64
root@morgental:~# ip link set foo up mtu 1468
root@morgental:~# ip -6 route show dev foo
fe80::/64 proto kernel metric 256
but on 3.13.1, no such route shows up. I can add it manually, though.
This broke our in-house IPv6 tunnel broker (which essentially uses link-local
addresses over GRE tunnels to bring up BGP sessions). Do you think you could
have a look?
