Description
PR:#8779 leads to failure of Test Case tests.route.test_default_route.test_default_route_with_bgp_flap by addition of 'AZNGHub' device type for Upstream T3 Neighbors in minigraph templates.
The Test cases uses the function get_upstream_neigh, which considers only T3 Neighbors which are not of type "AZNGHub".
As the PR have changed the device type, and adds "AZNGHub" and in default 50% type, it impacts the test case, as the test case needs the count of uplink route nexthops needs to same as the number Upstream Neighbor as per the topology.

Describe the results you received:
"Default route nexthops doesn't match the testbed topology"
The count of the Uplink Route is not matching with the Upstream Neighbor as per the topology(reading data from configfacts)

Describe the results you expected:
The count of the Uplink Route should match with the Upstream Neighbor as per the topology(reading data from configfacts)
