Well -
The command has been there for a few days now, and no result. I'll do a few
3
finger salutes to the routers and see if that clears the problem.
Thanks.
DMT

From RIP's standpoint, it'd take 4 minutes to flush a route after it goes
away....
From PPP's standpoint, that route will still exist even after the "no peer
neighbor-route" command is issued until the link resets. The neighbor route
is
part of the PPP negotiation phase, so if you've already negotiated/exchanged
it,
it's not going to just magically go away.
Try a shut/no shut and see what happens.

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.
