Hi everyone. I'm new to cisco and i was wondering if it's possible to connect a 1841 running IOS 12.4 to a mikrotik L2TP/IPSec server. The reason i do not wish to use Cisco as the server is because it is going to be used with a dynamic Public IP. TIA.
Solved! Go to Solution.

are the router accept the crypto command ? if it accept it and the virtual and pseudo is not accept then this limit in router plaftorm not in IOS image.
crypto is accept only by IOS image 9k (security advance)

Thanks. I'm trying for 2 days now to find a solution but i'm stuck at the first step, it seems that the following command is not available.
pseudowire-class L2TP_PW encapsulation l2tpv2 ip local interface FastEthernet0/1

Im stuck at creating a virtual ppp.
cisco-2.backup.ckrco(config)#interface Virtual-PPP1
^
% Invalid input detected at '^' marker.
cisco-2.backup.ckrco(config)#
p.s. this is a second cisco running the exact same conf (this is used for testing and then implementing to the first one).

When i open the link (http://www.cisco.com/en/US/partner/prod/collateral/routers/ps5854/prod_bulletin0900aecd802a9493.html) as stated in the solution reply, i get "access denied".

the answer for your issue
The interface virtual-ppp and pseudoeire configuration requires the l2tpv3 pseudoeire-class feature, which is only available in the -entservicesk9-, -spservicesk9-, -advipservicesk9-, or -adventerprisek9- IOS feature sets. That's why you can't configure this in the -ipvoice_ivs- feature set as you have. You may want to upgrade the feature set and see if that helps.
for link sometimes cisco remove the doc. so the link will not available anymore

Sorry, not sure i understand what i need to do. Do i need to upgrade the IOS or buy a new license?
05-20-2023 04:35 AM - edited 05-20-2023 04:39 AM
upgrade to 9K IOS image
05-20-2023 04:36 AM
You mean i need a new router?
