We operate 2x networks.
One of them runs Cisco 7201 routers as route reflectors,=20
while the other runs Juniper M120 routers.
The large Juniper routers were due to particular BGP AFI's=20
that Cisco IOS does not support (yet).

You can certainly use any device in your network to=20
originate your allocations. We just use the route reflectors=20
because it is a natural fit, but you can use any device=20
provided it would be as stable and independent as a route=20
reflector.
The last thing you want is a blackhole or a route going away=20
because your backhaul failed or your customer DoS'ed your=20
edge router :-).

There was a time when networks were ran without prefix=20
lists, BGP communities or even route maps. I'm too young to=20
have ever experienced those times, but I always joke with a=20
friend (from those times) about how good we have it today,=20
and how hard life must have been for Internet engineers of=20
old :-).
If you have the opportunity, I'd advise against operating=20
without these very useful tools.

I'm sure there are several networks out there that are=20
intimidated by additional BGP features such as communities,=20
advanced routing policy, e.t.c. They do survive without=20
having to deal with this, probably because they're networks=20
are small and the pain is better than trying something new.=20
But I certainly wouldn't recommend it to anyone (except, as=20
Randy would say, my competitors).
