Conditions
1. BGP IPv4 Unicast AFI not configured in global table.
2. Trigger the issue by config VRF import (i.e "import from default-vrf route-policy") and BGP IPv4 Unicast AFI in one configuration commit.
Workaround
Make sure BGP IPv4 unicast AFI is configured before any dynamic leaking configuration under VRF.
Recover way is to re-configure the import from default VRF.
