EEM nat overload weirdness

Patrick McHenry
Level 4

‎08-27-2012 01:20 PM - edited ‎03-07-2019 08:33 AM

I've configured the EEM to bring up a backup interface. In the EEM config, I have - action A37 cli command "ip nat inside source list nat_acl interface GigabitEthernet0/2 overload". This makes g0/2 the source of the nat translations. When I fail back to the primary interface g0/0, I  have action A35 cli command "ip nat inside source list nat_acl interface GigabitEthernet0/0 overload", but it doesn't seem to take.

And when I do a "show run | i nat", I get: " ip nat inside source list nat_acl interface GigabitEthernet0/2 overload'

But the weird thing is that it still works. I have a phone and a laptop connected to it and can make calls and the laptop can traverse the Internet. Does the router just use the interface that is available?     

Any ideas why this still works and any ideas how I can get EEM to change the nat list?

Thanks, Pat.

Patrick,

My first thought is that when you try to remove a nat statement and there are translations currently in use, it will prompt you to remove those translations (basically clear the nat table). If you answer anything other than "Y", it will kick you back to the prompt without clearing them. I've not tested this yet, but you may be able to answer the prompt in your eem script that you're clearing it in:

R2(config)#no ip nat insid source list 101 inter fa0/0 overload

Dynamic mapping in use, do you want to delete all entries? [no]:

So, in your eem script you would need to answer this to delete the line. Create a new action after your "no ip nat ..." line:

action a36 cli command "no ip nat inside source list nat_acl interface GigabitEthernet0/2 overload" pattern "delete all entries"

action a37 cli command "yes"

This would delete the line completely. You then could add the new line after this action....

HTH,

I tried this manually but it still wouldn't allow me to delete the line.

But, why does this stll work? Does the router just find a way out? It kinda bothers me. Is there any other config you would like to see?

Thanks, Pat

Pat,

Sure...can you post your ip nat lines and your eem script? It shouldn't work if the backup interface is truly not being used. How do you have the backup interface configured? Is it configured on the primary or is it an interface that's always up, but you prefer it only when your primary goes down? What happened when you tried to delete the line manually?

John

I have the Event Manager FAIL__TO_BACKUP_INTERFACE shut go/2, and it is shut at the moment. I just noticed though that my laptop cannot ping public addresses though but, I can through the router.

I have the backup interface down when not used. It comes up and builds a tunnel when the primary pings fail.

Thanks again.

Pat,

When you are pinging from the router, it's locally generated and sources from the outside interface which would explain why you get a response while doing this from the router but not doing from a pc. You can also test this by pinging a public address from the router and then sourcing from the inside interface that's part of the subnet to be natted. It should fail if nat truly isn't working.

What happens when you try to remove your nat statement manually? Does it do anything at all? Aside from your script, what I would do is, unless I'm not seeing it, is to remove the nat statement during failover before applying the new nat statement along with the pattern command from my earlier post. We first need to figure out what the router does when trying to remove the nat statement manually.

HTH,

John

Pat,

I see the following line:

%Dynamic mapping in use, cannot change

What I would do is change the eem script to delete the line completely before applying the new line. I would have to test this, but have you tried that? I could set up a lab this afternoon if needed.

So, what you're doing is bringing down g0/2 and then adding

action A35 cli command "ip nat inside source list nat_acl interface GigabitEthernet0/0 overload"

Then I think you're getting the above error because you're trying to nat the same acl to different outside interfaces (again, I'd have to test). What I would do is try deleting the ip nat statement and see if you can delete the mappings as in my above post. If that works, then change your script to:

action A33 cli command "no ip nat inside source list nat_acl interfac g0/2 overload" pattern "entries"

action A34 cli command "yes"

action A35 cli command "ip nat inside source list nat_acl interface GigabitEthernet0/0 overload"

Same thing for your fail_to_backup script:

action A34 cli command "no ip nat inside source list nat_acl interface GigabitEthernet0/0 overload" pattern "entries"

action A35 cli command "yes"

action A36 cli command "ip nat inside source list nat_acl interface GigabitEthernet0/2 overload"

I tried it and it worked going from the primary to the backup. The nat statement changed to g0/2 and all was good but, when I went to the primary again I got the death sequence when I tried to delete the g0/2 nat statement - I highlighted in bold. After, I entered the nat statement manually for g0/0 and it took but then, I had to down and up interface g0/0 for it to build the tunnel again.

Pat,

Can you post the newly revised eem script Fail_Back_To_Primary_Interface?

Pat,

I couldn't find anything about the error that you're receiving, but here's a thought. The run time for a script is 20 seconds. It looks like you're getting close to that threshold. I'd recommend, if you can, to raise the max run time on your event line and see if that helps.

Try changing:

event syslog pattern "1 ip sla 10 reachability Down->Up"

To:

event syslog pattern "1 ip sla 10 reachability Down->Up" maxrun 45

Let's see if that keeps the script from erroring out.

HTH,

John
