The bgp_bmp and bgp_bmp_vrf tests use similar routines
to test the bmp, but are duplicates. Gather the bgp_bmp
and the bgp_bmp_vrf tests in a single bgp_bmp folder.
- Create a bgpbmp.py library under the bgp_bmp test folder
- The bgp_bmp and bgp_bmp_vrf test are renamed to bgp_bmp_1
and bgp_bmp_2 test.
- Maintain separate folder for config and output results. Adapt
the bgp_bmp library accordingly.
- The json output for bgp_bmp_2 test has no referenc to hostame.
