Hi all,
I want to login PC1 through SSH2 where vpp is running, and the VPP is used
as the VXLAN translate center(only 1 ip).
However, I found some error!
Data from vxlan tunnel 1 were dropped, which should be decaped at one
vxlan-tunnel-1 and transmited out from vxlan-tunnel-2.
How can I achieve my goal?
Help please!
