Hi All
I having a few problems with eigrp authentication. Routers R7 and R8 are connected via serial. I have tested layer 1-3 connectivity which is OK. eigrp is forming neighbors ok when authentication is not configured. OSPF is also running and is working OK with adj being formed etc. The relevent portion of the config are below:
The debug from R7 is as follows:
*Mar 1 00:28:21.577: EIGRP: Serial0/1: ignored packet from 150.50.5.69, opcode
= 5 (missing authentication)
R8
interface Serial0
ip address 150.50.5.69 255.255.255.224
ip authentication mode eigrp 1 md5
ip authentication key-chain eigrp 1 ccie
no fair-queue
router eigrp 1
network 150.50.4.0 0.0.0.255
network 150.50.5.64 0.0.0.31
