push-continuation

[reynir]

I discovered in the OpenVPN code that there is a (non-user facing) option push-continuation <n>. This seems to be used for large push replies that need to be split up over multiple messages. I have not found any documentation, but it seems only push-continuation 1 and push-continuation 2 is sent. The latter is, from my understanding, signalling that the push reply is split up. I am guessing push-continuation 1 signals no more push replies are to be expected.

There is a value PUSH_BUNDLE_SIZE of 1024 which I think is the maximum push reply size (whatever that means).

The push reply may be too large if for example the server is pushing many routes.
