Hi Team,
I just had an interesting experience configuring my second hub, I forgot too add the no split horizon eigrp # command. I was getting the following errors:
Mar 1 01:23:08.639: IP-EIGRP(Default-IP-Routing-Table:1): 192.168.254.0/24 - do advertise out Tunnel2
*Mar 1 01:23:08.639: IP-EIGRP(Default-IP-Routing-Table:1): Int 192.168.254.0/24 metric 128256 - 256 128000
*Mar 1 01:23:08.723: IP-EIGRP(Default-IP-Routing-Table:1): Processing incoming UPDATE packet
*Mar 1 01:23:08.723: IP-EIGRP(Default-IP-Routing-Table:1): Int 192.168.254.0/24 M 4294967295 - 284444416 4294967295 SM 4294967295 - 284444416 4294967295
What was interesting is that I still able to establish neighbors though, before adding split horizon on tunnel 2 interface. I was having issues getting 192.168.254.0 on my spoke’s routing table. So I added the network statement as follows and it worked without split horizon on:
router eigrp 1
net 192.168.254.0
before I had it like this and it wasn’t working.
router eigrp 1
net 192.168.0.0
I hadn’t seen this error message so I was a little confused by this. I guess this is the error message for slit horizon not being enabled?
Thanks
