Most if not all IGPs can be configured to work without multicast.  Now if
you're talking IPv6 you may have some issuesÅ

Yes, that's another part of the conversation, encouraging the use of
an IGP, which has been a source of trouble for them because of broken
wireless bridges from a very commonly used vendor that randomly eat
multicast packets, so it's not as straightforward as it should be.

Ok, fair enough. My first experience with PBR was as a summer intern in
the mid-1990s who inherited management of a large ATM network that had
a big VPN-esque thing built entirely that way and with no
documentation. It certainly felt evil at the time. ;)
