[PATCH v4 3/3] tests: enhance bgpd testing with label value
philippe.guibert at 6wind
Oct 11, 2016, 12:57 AM
Post #1 of 1 (142 views)

bgp NLRI has a specific format for label, terminating with bottom
of stack bit. This value is updated in all BGP attribute tests. A
specific test has been added to check for a list of labels contained
in a single NLRI.
