FS#1361 - Unable to configure multiple IPv6 prefixes in luci

[openwrt-bot]

diego:

I'm running OpenWrt SNAPSHOT r6074-267873a / LuCI Master (git-18.039.58622-76f9f5e) on Alpha ASL26555 (16M). Tried also in 15.05.1, same behavior.

I'm running a 6in4 tunnel for IPv6 connectivity, provided by Hurricane Electric.

HE delegates to me two IPv6 prefixes, a /64 and a /48.
I've set up the tunnel in lucy effortlessly, but just the /48 was working.

After pulling my hair for a long time, I figured out to add by hand another ip6prefix line to my tunnel interface in /etc/config/network

In lucy, There's a field named 'IPv6 routed prefix' that only allows exactly one prefix (and is the last one listed in /etc/config/network interface declaration). The field should be 'extensible', so multiple prefixes could be added, much like 'forwarding DNS' settings in Network/DHCP and DNS settings in lucy.

Well, I was too happy too early

Adding two ip6prefix lines to /etc/default/network is useless, just the last one is applied.

So I'm unable to route two prefixes over a 6in4 tunnel in openwrt/LEDE. That config is perfectly valid and in fact is running fine in linux.

ip6prefix should take a list of prefixes, or at least multiple sentences should be honored. And of course, lucy should be modified to reflect that.

jow-:

Not a LuCI specific problem since the underlying protocol backends do not support multiple prefix in their configuration yet.
