Subject: Redistribution best practices

Dear GS,

Whenever i redistribute from a higher Administrative Distance Protocol
(RIP) to a lower administrative distance protocol (OSPF), i use "distance
ospf external 130" command in ospf routing process as a best practice to
avoid reflect back routes from causing a loop.

Using this practice is useful, if the next downstream neighbor in OSPF
domain is a HUB with split horizon disabled.

But if the downstream neighbor is a point-to-point end router, than using
the "distance command" does not make sense if the split horizon is enabled.

But as a safety measure can i use the "distance" command in the above point
to point topology? what if the proctor disable split horizon the other end,
it will help me in this situation?

using "distance ospf external" command as a safety measure will cause me to
loose points in the R/S lab even if it is not required??

please answer
