Dear all
my test uses two vrfs in vpp：
vrf A: interface(G0) with pulic ip address(172.16.0.73/24) exists，and i also
did "nat44 add address xxx tenant-vrf A"/"set interface nat44 out G0
output-feature"/"nat44 forwarding enable"
vrf B: there is no public ip address, so need to access the internet through
vfr A interface G0, so i did "ip route add 172.16.0.47/32 table B via 0.0.0.0
next-hop-table A",but that does not work.
do I missing something or any suggestion ?
detail configurations shows below：
