Description

This will wreak merry havoc with the babel protocol, among others:

So here we are with 2 network ports and 2 radios, and a bunch of virtual bridges. Yet we have:

root@OpenWrt:~# ip -6 addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 fe80::c63d:c7ff:fe8b:6e1a/64 scope link
valid_lft forever preferred_lft forever
8: br-lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
inet6 fe80::c63d:c7ff:fe8b:6e1a/64 scope link
valid_lft forever preferred_lft forever
9: br-guest: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500
inet6 fe80::c63d:c7ff:fe8b:6e1a/64 scope link
valid_lft forever preferred_lft forever
10: br-meshlink0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 4
inet6 fe80::c63d:c7ff:fe8b:6e1a/64 scope link
valid_lft forever preferred_lft forever
11: br-meshlink1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 4
inet6 fe80::c63d:c7ff:fe8b:6e1a/64 scope link
valid_lft forever preferred_lft forever

All the same!

And no eth1 at all! yet on the ipv4 side we have:

root@OpenWrt:~# ip addr

constructing a fe:vlan::eui/64 seems closer to the right thing.

I'm not sure this is still a problem at all.

Bridging is no longer used in cerowrt. If others wish to bridge widely disparate networking interfaces together, they deserve all the pain they get.
