[iris00522]

Why I did it

1.set vrf and binf interface
sudo config vlan add 2000
sudo config vrf add Vrf1
sudo config interface vrf bind Vlan2000 Vrf1
sudo config interface ip add Vlan2000 10.0.0.66/31
2.check state db
127.0.0.1:6379[6]> keys VRF
1) "VRF_TABLE|Vrf1"
2) "VRF_OBJECT_TABLE|Vrf1"
3.config reload
config reload -y
2.check state db , and the VRF_OBJECT_TABLE still exist
127.0.0.1:6379[6]> keys VRF
1) "VRF_OBJECT_TABLE|Vrf1"
127.0.0.1:6379[6]>
