Enable support for outputting Huawei as-path access-lists

[wbergg]

Add support for Huawei devices (-H) to output Huawei as-path access-lists.

Eg. ./bgpq3 -f 39651 AS-COMHEM -H ip as-path-filter NN permit ^39651(39651)*$ ip as-path-filter NN permit ^39651([0-9]+)*_(25037|28942|56563|59835)$

Can you provide link to Huawei documentation, so I can implement prefix-lists too ?

[wbergg]

You need a login to see the documentation, I took a screenshot of both as-path and prefix-lists: https://wberg.com/huawei.png

Done, pushed to github head. Two notes:

• new flag is called -U, not -H
• I'm not sure that removing configuration is done with 'undo' prefix, can you confirm ?

Example:

./bgpq3 -Uf 39651 AS-COMHEM undo ip as-path-filter NN ip as-path-filter NN permit ^39651(39651)$ ip as-path-filter NN permit ^39651([0-9]+)_(25037|28942|56563|59835)$

That's correct, undo ip as-path-filter < name > !
