hi guys, I have tested basic eigrp over hub %spoke topolohy.In the ınternet I have read that in eigrp hello packets do have ttl value 2 so just only disable ip split horizon on the hub would be enough in order to get spokes eigrb neighbor.Is that right? Or doI have to use negihbor command?
On the other hand I tested and without neihbor command can not get spokes negihbor. r2 ----hub Rack1R2#sh run | s eigrp ip authentication key-chain eigrp 100 2 no ip split-horizon eigrp 100 router eigrp 100 network 150.1.2.2 0.0.0.0 network 183.1.28.2 0.0.0.0 network 183.1.123.2 0.0.0.0 no auto-summary eigrp router-id 150.1.2.2 Rack1R2#sh run int s0/0 Building configuration...
