Hey Group,
I recently pondered something while at work and nobody could give me a
strait answer. Actually I feel a little embarrassed asking this due to me
being an NP and I feel like I should know this. Guess this type of thing
doesn't come up much around me. Question is: Can poison reverse

But I thought that I'd seen or heard of using split horizon with
OSPF...maybe I'm thinking of Frame Relay...long day I guess...

OSPF does use Split horizon. I don't think OSPF uses PR because PR sets
the
route to infinity and I'm not sure what an ' infinity' cost would mean i
caused by the way Distance-vector protocols converge.

OSPF uses split-horizon? I don't think this is correct. I hate to be quick
to reply but there is no reason for OSPF to use split horizon. OSPF sends
updates to all adjacent neighbors,
rizon must be disabled on the
hub(unless the hub is configured for point-to-point to each spoke)

Leigh Anne Chisholm,
Actually by default on IP interfaces:
Split-horizon is disabled on Frame-relay physical interfaces
Split-horizon is enabled on Frame-relay point-to-point and multipoint
subinterfaces
(but who cares it's configurable)

Judging by the web page on Cisco's site
(http://www.cisco.com/warp/public/779/smbiz/service/knowledge/wan/subifs.htm),
it appears as if split-horizon is disabled for routing IP on physical
