The nexthop metric should be added to AIGP when calculating the bestpath in bgp_path_info_cmp(). Signed-off-by: Enke Chen <enchen@paloaltonetworks.com> (cherry picked from commit 081422e)
Fix and adjust the topotest post the fix for route selection with AIGP. When there are multiple IGP domains (OSPF in this case), the nexthop for a BGP route with the AIGP attribute must be resolved in its own IGP domain. The changes in r2/bgpd.conf and r3/bgpd.conf are needed as incorrect IGP metrics are received from NHT for the recursive nexthops. Once the issue is resolved, the changes can be reverted.
