If the following is issued on a Cisco router:
frame-relay map ip 10.1.1.1 200
What will be the end result ? (select all that apply)
a) Split horizon is disabled
b) Inverse ARP is disabled
c) Inverse ARP is enabled
d) Split horizon is enabled
I see that answer b) is correct for sure.
However, I am puzzled by a) and d).
Is there any affect in split horizon at all ? In my view, I think that split horizon would remain enabled, and therefore answer d) would be correct as well.
Can someone there confirm whether I am right ?

Hi,
IMHO, the only correct answer is b). Split horizon is a function of routing protocols and applies when you use multiaccess interfaces. Now, on a FR multiaccess interface you can either create IP to DLCI mappings manually or use inverse-ARP. The fact that you use one or the other has absolutely no impact on split-horizon. The fact remains that the interface is still a multiaccess interface.
