Re: operational problems at mae-west?

There's a hack around it (not pretty...) -- use physically
different LAN to propagate routing updates, with NEXT-HOPs
pointing to the "data LAN" interfaces.

The problem with that solution is that if data LAN fails,
there's no way to learn about it at BGP level.  That is due
to the unfortunate property of BGP (and many other routing
protocols) that it uses the same transport to propagate
keepalives and routing updates.

SPD (IP precedence) will not affect the prioritzation that the
gigaswitch applies (which is no prioritization).
