Hi All,
I have a simple question (hopefully) re. RIP authentication.
I have two routers directly connected via serial interfaces
R2 S1 <----------> S0 R1 Encap is HDLC (very simple config)
I'm trying to configure simple RIP authentication between the two - no
luck.
Here are the relevant configs from both
~~~~~~~~
R2
~~~~~~~~
!
key chain RIP_Auth
key 1
key-string cisco
accept-lifetime 13:27:00 Apr 1 2003 infinite
send-lifetime 13:27:00 Apr 1 2003 infinite
key 2
key-string cisco
key chain keychain
key 2
key-string cisco
!
interface Serial1
ip address 10.21.1.1 255.255.0.0
ip rip send version 2
ip rip receive version 2
ip rip authentication mode md5
ip rip authentication key-chain keychain
clockrate 125000

R1

key chain RIP_Auth
key 1
key-string cisco
accept-lifetime 13:27:00 Apr 1 2003 infinite
send-lifetime 13:27:00 Apr 1 2003 infinite
key 2
key-string cisco
key chain keychain
key 2
key-string cisco

!
interface Serial0
ip address 10.21.1.2 255.255.0.0
ip directed-broadcast
ip rip send version 2
ip rip receive version 2
ip rip authentication mode md5
ip rip authentication key-chain keychain
logging event subif-link-status
fair-queue
a debug of ip rip shows:
00:29:43: RIP: ignored v2 packet from 10.21.1.1 (invalid authentication)
I've tried clear authentication and still nothing.
If anyone can enlighten me that would be great.
Thanks in advance,
Jim
Ps. Clock are synchronised.
