Is it possible to use OER in Cisco 1812?

Question

Cisco

Acquired recently in 1812 for household needs. I have two uplinks from two different providers. I wanted balancing and other intellectual goodies. I set up OER policies, but how did it come to register NAT

ip nat inside source route-map ISP1 interface FastEthernet0 overload <b>oer</b><br/>
% Invalid input detected at '^' marker.

And now I can’t find the answer - either 1812 can’t OER, or the current IOS can’t. Googled everything he could.
Cisco IOS Software, C181X Software (C181X-ADVIPSERVICESK9-M), Version 12.4(6)T6, RELEASE SOFTWARE (fc2
)
Thanks in advance.

Answer 1

You can not google, but use Cisco Feature Navigator , which says that OER is available for 1812 with Advanced IP Services and Advanced Enterprise Services features.
As well as the documentation for the feature itself , which says that it appeared in 12.3(8)T.
So your device fits all the conditions, it should work.

Answer 2

OER Earned. In my version of IOS, as I understand it, it automatically initiates OER everywhere.
Now there is a problem with port forwarding to both providers at the same time. Does anyone know the solution?
