I see I was to unspecific. The sentence I mentioned from cisco was only related to EIGRP, but I've posted only a snapshot of the chapter, so that's why it maybe didn't show the right context. But is it correct that eigrp split horizon is diabled by default on physical serial interfaces running frame-relay? --------No, you will have disable it by using "no ip split-horizon eigrp as-number" R1#sh running-config interface serial 1/0.0 Building configuration... Current configuration : 143 bytes ! interface Serial1/0 ip address 1.1.1.1 255.255.255.252 encapsulation frame-relay no ip split-horizon eigrp 1 ............. ............. serial restart-delay 0 end Where can I find a detailed description regarding eigrp split horizon and the different interface types? Uncle google is your friend, a simple search will get you 100z of links. J regards Roger Von: Masood Ahmad Shah [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 15.

Split horizon behavior is turned on by default. In order to disable the split horizon behavior, use the "no ip split-horizon eigrp as-number" interface command.

Is the following correct, taken from a Cisco Book:" Most interface types enable split horizon by default, with the notable exception of a physical serial interface configured for frame-relay" If that's right, why do we have in LAB21 on R4 on the Serial0/0/0 no ip split horizon eigrp configured? This confuses me... thank you Roger
