[opensuse] adding static ipv6 routes with YaST
I'll be testing this again later today, but last night I was having trouble setting up static IPv6 routes with YaST. They were simply never written to /etc/sysconfig/network/routes, nor was the current route table updated. I wanted to add e.g. fe80::1 as default gateway via ethX. 2001:DB8:1234::/48 on ethY. I tried on two different systems, 13.2 and Leap.

It wasn't just me working too late last night, it still doesn't work. https://bugzilla.opensuse.org/show_bug.cgi?id=961105 -- Per Jessen, Zürich (4.8°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Where is fe80::1 coming from? Normally the link local address for the router is used. As the link local address is based on the MAC address, I doubt you'd see one ending in ::1. Also, I haven't heard of using a global unicast address for a router. As I mentioned, it's normally the link local address that's used. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

fe80::1 is the router, it's quite a common address to use.

That use is for default route redundancy, where the routers are assigned a virtual address, which 2 or more routers can respond to. Typically one does all the work, with the other on standby, ready to take over when the first fails. Read up on HSRP and VRRP for more info. Are you setting up redundant paths? When I look at my own network, the router has the regular link local address, which the other devices use for routing and also a global unicast address ending in ::1. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not at the moment, but afaict it matters not. Assigning fe80::1 to each router means not having to fiddle with the actual link-local address. Anyway, it works fine, except YaST can't assign static ipv6 routes. -- Per Jessen, Zürich (4.6°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
