Im gonna add the relevant file here for you. But before that, i must say that i didn't configure subinterfaces. Just went with IARP then static mapping. Routers see each other. However, when i add hosts to each router and ping other routers from that host, packet can't get back! "request timed out" shows up. I wanna be sure that this is because split horizon! Cos, even routers see each other and ping successfully, i can not see anything rather than"directly connected" on the routing table. Site won't add my .pkt file. So, i need to upload it somewhere else. 2shared - file upload

Shanman Member Posts: 223Just a quick thing to check is your firewall. If you are on windows try disabling it and then ping. You can check your arp table on the host as well.

I think he's using packet tracer.In order to succeed, your desire for success should be greater than your fear of failure.

Solved the issue but not sure by disabling split horizon on the hub oradvertising all networks including the one all routers know.Monster PC specs(Packard Bell VR46) : Intel Celeron Dual-Core 1.2 GHz CPU , 4096 MB DDR3 RAM, Intel Media Graphics (R) 4 Family with IntelGMA 4500 M HD graphics.

This means they won't send the route back out the interface it was learned (the logic here being you sent it to me why should i send it back) because of the way FR works in hub and spoke it wasn't sending the updates out as they were coming in on the same interfaceMonster PC specs(Packard Bell VR46) : Intel Celeron Dual-Core 1.2 GHz CPU , 4096 MB DDR3 RAM, Intel Media Graphics (R) 4 Family with IntelGMA 4500 M HD graphics.

zrockstar Member Posts: 378sorry, not to insult you but EIGRP is not a distance vector protocol. You probably were gonna say IGRP, rather. However, in my case, i am suspicous about why i should advertise the network known by all routers already!
Actually EIGRP is a distance vector routing protocol. -
NetworkVeteran Member Posts: 2,338 ■■■■■■■■□□sorry, not to insult you but EIGRP is not a distance vector protocol.
From Cisco's website:
"EIGRP is an enhanced distance vector protocol, relying on the Diffused Update Algorithm (DUAL) to calculate the shortest path to a destination within a network." -

In a typical frame-relay hub-and-spoke topology, the spokes form adjacencies with the Hub, but not with one another. If you add network 192.168.32.0 to SpokeA, it will tell the Hub; it won't tell SpokeB. Therefore, for dynamic and full network connectivity, we need the Hub to relay routes between spokes. It needs to tell SpokeB about the new network. It won't do this--assuming SpokeA and SpokeB are both reached via the same Hub interface--without configuring a form of 'no ip split-horizon' on that interface.
