I'm trying to configure L2TP tunneling between cisco 1841 and cisco 2811.
When I configure L2TP tunneling, I need to execute "pseudowire-class" command.
However, my cisco 1841 doesn't support the command.
The IOS release of this cisco 1841 is 12.4(19), and the feature set is "Advanced Security".
Do you know why the cisco 1841 doesn't support the "pseudowire-class" command?
