Here was the initial configuration for this interface - I have the no peer
neighbor-route. The route is still advertised.
Here is the configuration:
interface Serial1/1
ip address 172.16.35.5 255.255.255.0
ip pim dense-mode
encapsulation ppp
ip summary-address rip 172.16.35.0 255.255.255.0
ipv6 address FEC0::35:5/125
ipv6 rip rip enable
no peer neighbor-route

Subject: RE: /32 advertisement with Rip and PPP interface:
PPP interfaces automatically inject a "peer neighbor-route". This was a
feature introduced a long, long time ago (in a galaxy far, far away known as
Modem-Land) where we had lots of "ip unnumbered" interfaces and therefore
reachability problems without a plethora of static routes.
You can get rid of it by putting "no peer neighbor-route" under the PPP
interface.
