I also want to prevent adverts out and distribute-list gateway doesnt
appear to work outbound for EIGRP.

Paul,
Changing those values would break all neighbours on an interface,
anything to kill just the one?
For example:
172.16.1.1
172.16.1.2
172.16.1.3 <- I temporarily want to prevent this neighbour.
172.16.1.4
Thanks,
Mike

In OSPF a neighbor relationship will not be formed if any of the
following
mismatch:
hello/dead interval
area id
stub flag
authentication
subnet mask
mtu
So for example, if you change the hello interval on one side, the
neighbor
will not form. You can see this by doing a "debug ip ospf adj".
For EIGRP, you can try changing the K values or Autonomous System
number.
EIGRP will for a relationship even if the hello values do not match.
Take care,
Paul Borghese
