@thomas-mangin Hi. Just wanted to check regarding flow tcp-flag. In https://groups.google.com/forum/#!searchin/exabgp-users/colon/exabgp-users/nCJPndfK3EY/mxygwg5kMqAJ it was mentioned JUNOS uses : (colon) which actually matches for any packet with the flag set, as opposed to = (equal) which is a firm match for the exact tcp flag combination. How do I do the : type of match on exabgp?

I forgot about this mail thread. Could you please opeen an issue on github so I do not miss it twice.
@hengchai - I am not sure how Juniper works. I assume that : generates a list of all possible option for the packet which matches the flag. There is no such feature with ExaBGP, I could add it to the parser tho. If you could send me a example of what Juniper does and how they encode it, it would be most useful.
reading the thread again, I am missing this encoding and should add it.
