Re: OT: Logical Bundle

Hmm, what's in there after the routers ? Because if the rest of the
things are controlled, there's nothing really hard that prevents using
the same address for both ciscos and both huaweis. Anycast in IPv4 :)

Just have some routing protocol share the reachability info and H1 will
go to C1 direct as long as C1 is there, and to C2 if it's not.
May be some secondary addresses and tracking magic to change statics if
all else fails :)

Then use BGP to publish everything with those anycast next hops and...
voila. A nice nightmere to support :)

But fun.
