Any way to get rid of backbone ip ospf network point-to-multipoint /32
routes?
I think the answer is no, but wanted to double check.
I tried an area 0 range command on the afflicted routers with no luck.

I also have an unrelated question.
Why does version 1 rip round a /32 192.168.x.x loopback to a /24? I
have no summary turned on. I understand this is a native class C route,
but it doesn't summarize the class B network I'm also using. To me, no
auto summary should mean no auto summary. Configs below.

<----- Why? This was a /32 on the other router.
If it's going to auto summary anyway, why not a 172.30.0.0/16 route too?
Thanks in Advance,
Michael
P.S. Also noticed that if you import /32 192.168.x.x routes, they become
/24 routes in rip.
