RE: IPSec problem using CA server

Is there a reason why the time on the two devices is so far apart? In
general, the devices are usually within a few minutes of each other.

Marvin,

 

Yes, I searched on this error and saw that most of the people were able to
resolve this issue fixing time on routers and the CA. Below is a snapshot
from my two routers showing the certificate validity times and clock and I
can't see anything wrong with it, may be one of you will find something that
I am overlooking:

 

************************************************************

Rack1R1:

Validity Date:

   start date: 00:00:00 UTC Feb 22 2007

   end date: 23:59:59 UTC Apr 23 2007

 

Show clock ==> 06:08:29.861 UTC Fri Feb 23 2007

************************************************************
Validity Date:

    start date: 00:00:00 UTC Feb 22 2007

    end date: 23:59:59 UTC Apr 23 2007

 

Show clock ==> 23:04:43.849 UTC Fri Feb 23 2007

**************************************************************

 

Thanks for your help.

Have you checked the time set on your devices with respect to the CA server?

Subject: IPSec problem using CA server

All,

I am currently testing IPSec to work with a CA server. I have configured
two routers (connected via a LAN connection) and have retrieved certificates
on both routers successfully but when I try to bring up the tunnel by
pinging one router from the other, I get the following message:

%CRYPTO-5-IKMP_INVAL_CERT: Certificate received from x.x.x.x is bad: CA
request failed

Can someone pls let me know what could be a common cause - if I remove
crypto map from the interfaces, things start to work. BTW, I have
configured a tunnel interface using the physical LAN connection between the
routers and have crypto map applied to both tunnel and lan interfaces.

TIA

Tony.
