10 ... TODO: Rename this file after Beryllium is out, for example to basic.robot
12 ... Test suite performs basic BGP functional test cases:
13 ... BGP peer initiated coonection
14 ... - introduce and check 3 prefixes in one update message
15 ... ODL controller initiated coonection:
16 ... - introduce and check 3 prefixes in one update message
17 ... - introduce 2 prefixes in first update message and then additional 2 prefixes
18 ... in another update while the very first prefix is withdrawn
19 ... - introduce 3 prefixes and try to withdraw the first one
20 ... (to be ignored by controller) in a single update message
22 ... Brief description how to perform BGP functional test:
