sure, but the interface report serves a different purpose. The only routing protocols that honor split horizon are IGRP and RIP. BGP, OSPF and EIGRP use topology tables of one kind or another ( stop steaming at the ears, Howard :-> ) it is highly feasible that any of these latter protocols would need to advertise routes back out the interface from which they were learned. Eg DR, BDR, etc. BGP neighbor, etc. > > GigabitEthernet1/1 is up, line protocol is up > Internet address is 171.71.243.34/30 > Broadcast address is 255.255.255.255 > Address determined by non-volatile memory > MTU is 1500 bytes > Helper address is not set > Directed broadcast forwarding is disabled > Outgoing access list is not set > Inbound access list is not set > Proxy ARP is enabled > Local Proxy ARP is disabled > Security level is default > Split horizon is enabled > > Larry Letterman > Network Engineer > Cisco Systems > > > ----- Original Message ----- > From: Troy Leliard > To: [EMAIL PROTECTED] > Sent: Wednesday, March 05, 2003 4:57 AM > Subject: Re: Off Topic - just screwing around and what do I [7:64454] > > > Split Horizon for EIGRP ... dont think so. !!! > > Larry Letterman wrote: > > > > r3 sends to r2, then r2 sends back to r3.. > > you sure about that...split horizon should be enabled for > > eigrp and igrp..and igrp and eigrp will work together in the > > same as number..not sure about different as #'s.... > > > > Larry Letterman > > Network Engineer > > Cisco Systems > > > > > > ----- Original Message ----- > > From: The Long and Winding Road > > To: [EMAIL PROTECTED] > > Sent: Tuesday, March 04, 2003 11:04 PM > > Subject: Off Topic - just screwing around and what do I see? > > [7:64449] > > > > > > three routers in a circle. but that's irrelevant. > > > > inbound from r3-------r1--r2-----r3----->back to r1 > > > > > > I have IGRP between two of the routers.
