2017-09-13Add a name to the creation of an IP and MPLS tableNeale Ranns1-2/+2
Change-Id: I4b4648831551519b2ffb6f93255d28a4b8726c22 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-09-11FIB table add/delete APINeale Ranns1-1/+3
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>

- add/delete IPv6 VRF instances and verify results by parsing output of ip6_fib_dump API command and by traffic - small changes in assert_nothing_captured and get_capture to get logged unexpected packets Change-Id: I32207447be2df942e335aa9890ff52fb88e46597 Signed-off-by: Jan Gelety <jgelety@cisco.com>
