topotests: add bgp_nhg_topo2 test to check for bgp nhg cases
Browse files Browse the repository at this point in the history 
When not used by default, bgp nexthop group are not tested
against the following route entry added:
- route entry resolved over default route
- route entry resolved over itself
- route entry resolved over blackhole route
- route entry connected (case mplsvpn)
- route entry using ipv4 mapped ipv6 address

This test suite covers the above use cases.
