Michael,

I see from cco that syntax is the same.

[no] rip if_name default | passive [version [1 | 2]] [authentication [text |
md5 key (key_id)]]
Ensure that the key and key_id values are the same as in use on any other
device in your network that makes RIP Version 2 updates.

Could you do a sho rip from the pixel and deb rip upd from the router an d
tell us what is happening?
Rtr show key chain
Rtr deb rip upd

From cco:
Only Intel 10/100 and Gigabit interfaces support multicasting.
When RIP Version 2 is configured in passive mode with PIX Firewall software
Version 5.3 and higher, the PIX Firewall accepts RIP Version 2 multicast
updates with an IP destination of 224.0.0.9. For RIP Version 2 default mode,
the PIX Firewall will transmit default route updates using an IP destination
of 224.0.0.9. Configuring RIP Version 2 registers the multicast address
224.0.0.9 on the respective interface to be able to accept multicast RIP
Version 2 updates.

Also you want to go beyond PIXOS 6.2.1

Open PixOS 6.3.4

Hi,
 
I am not able to get PIX RIP authentication running using MD5. Without MD5,
the routing is fine, when I turned on MD5 using the following, PIX no longer
gets RIP routes, could you spot anything I am missing? thanks.
 
on PIX:
 
rip outside passive version 2 authentication md5 cisco 1
 
on Router:
!
key chain r3
 key 1
  key-string cisco
!
interface Ethernet0/0
 ip address 10.50.31.1 255.255.255.0
 ip rip authentication mode md5
 ip rip authentication key-chain r3
 half-duplex
!
 
thanks,
Michael
