Hi guys,
This is interesting but confusing.
R1, R2, and R3 are running eigrp over a hub and spoke f/r cloud with R2 as
the hub.
R1 doesn't ever see R3, the other spoke as an eigrp neighbor, but R3
sometimes sees R1 as a neighbor.
On R1, the neighbor state with R3 flaps up and down.
On R2, the hub, ip split-horizon has been disabled.
R3#sh ip ei n
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq

R3#uu

Notice the uptime for R1 (1831.1.123.1) is very small relative to R2.
Moments later.

And, I get these messages on R3:
R3#

Anyone know what's going on? And, know what should be done about this?
TIA, Tim
