RE: Question about split horizon & IPX [7:19232]
Cisco does actually let you turn off split horizon for AppleTalk RTMP. I don't think it is officially supported, but it does work. It's also not officially supported by the AppleTalk specification (Inside AppleTalk). So this got me wondering about IPX RIP. Of course, disabling split horizon is not officially supported for IPX RIP, per Novell's specification. And Cisco does not officially support turning it off either, but would the IOS let you do it anyway? The answer seems to be no on my routers running 11.0, but it would be worth a try on a more recent router (if my husband would let me buy new routers... ;-) Albany#config t Enter configuration commands, one per line. End with CNTL/Z.

Albany(config-if)#no ipx split-horizon eigrp ? Autonomous system number Albany(config-if)#no ipx split-horizon eigrp 10 Of course, as we all know, if you use EIGRP for AppleTalk or IPX, then you can disable split horizon.

Re: Question about split horizon & IPX [7:19232]
Yes and this is another reason you want to configure frame relay with p-to-p subinterfaces.

I did a lot of research on that topic last year when I developed Sybex's CCNA Virtual Test Center.

Re: Question about split horizon & IPX [7:19232]
For Cisco, the only IPX routing protocol that allows disabling of split-horizon is eigrp. See (watch URL wrap) http://www.cisco.com/warp/public/473/33.html for that and other IPX case studies, and search for split-horizon in the text for your specific issue. The solution given by Cisco is to use point-to-point sub-interfaces if using IPX RIP to work around the IPX split-horizon issue. - Original Message - From: "Phantom" To: Sent: Monday, September 10, 2001 12:06 AM Subject: Re: Question about split horizon & IPX [7:19232] > Hi > > Neither books give any details as to why you would do it.

Question about split horizon & IPX [7:19232]
Hi I am studying for CCIE Written, one of my books say that you can't disable split horizon for IPX the other says you can. Which one of these are correct and for which routing protocols can I do it.
