If you are running EFA 2.5.5 or above, run the following command:

efa tenant vrf create --tenant "ten1" --name "ten1vrf1" --routing-type "distributed" --rt-type import --rt 100:100 --rt-type export --rt 100:100 --rt-type import --rt 200:200 --rt-type export --rt 200:200 --rt-type import --rt 300:300 --rt-type export --rt 400:400 --max-path 8 --redistribute connected

efa tenant vrf create --tenant "ten2" --name "ten2vrf1" --routing-type "distributed" --rt-type import --rt 100:100 --rt-type export --rt 100:100 --rt-type import --rt 200:200 --rt-type export --rt 200:200 --rt-type import --rt 300:300 --rt-type export --rt 400:400 --max-path 8 --redistribute connected
