Re: Multiple OSPF keys on Hub and Spoke Frame Relay

This configuration always generates problems (many thread on this in the past), but it works. Please looks archives.
 Try to configure it in this way:
 
 * Configure MD5 auth between Hub and Spoke 1 first (no MD5 auth on the Hub for Spoke2 yet)
 * Make sure the neighbor relation ship between Hub and Spoke 1 is fine
 * Configure MD5 auth between Hub and Spoke 2.
 * Check the hub is in rollover for the first key you configured
 
 Rack1R5#sh ip ospf int s1/0 | b Roll
     Rollover in progress, 1 neighbor(s) using the old key(s):
       key id 35
 Rack1R5#

Subject: Multiple OSPF keys on Hub and Spoke Frame Relay

 This is from IE Vol2 lab 3 task 4.6

You have a hub and spoke frame relay using physical interfaces.
The task states to use a different OSPF key for each spoke.

The solution guide states to configure both keys on the hub with different
key numbers however when I configure this only one spoke is able to
authenticate and the other spoke does not establish adjacency.

Here is the setup and solution:

    R1
    /
R3
    \
    R5

R1:
ip ospf message-digest-key 13 md5 CISCO13
R5:
ip ospf message-digest-key 35 md5 CISCO35
R3: ip ospf message-digest-key 13 md5 CISCO13
ip ospf message-digest-key 35 md5 CISCO35

As I said only one spoke comes up (I can't remember which and my rack time
is up).

Any ideas are appreciated.
