It's nice to know that both of us can struggle with babel syntax. The
first line there doesn't parse. Should it?

out ip fd42:a3d6:5621::1/128 allow
out deny

Parses. the route appears elsewhere, it doesn't show up as a router,
but the box is unpingable via ipv6.

Dave, it's September.  Do you imagine what September looks like at university?

[Babel-users] babel on an otherwise transparent bridge

2016-09-07 Thread Dave Taht 
I have a box setup to be a transparent wifi/ethernet bridge. What I'd
like it to do is have a dedicated ipv6 ULA ip address for management
purposes (not using a vlan here), and announce that to the network,
but never offer
itself as a routing opportunity to anything on any side of the bridge, except
for stuff trying to get to that specific IP. It also needs to have a
route table internally to get around the network (snmp).

If I just blithely leave babel at the defaults, new devices on the bridge tend
to get routes from it, first, leading to a 30-60 second period where
those devices can (and do) choose that 2 hop route rather than the "1
hop" one.

out br-lan something deny?
in?
inflate the metric?
