"""
|
|
Basic tunnel connectivity test
|
|
|
|
Set up a tunnel between two DUTs, host connected to the first DUT. Enable
|
|
IP forwarding on first DUT's interface to host and the tunnel interface to
|
|
the second DUT. On host, add route to IP network of second DUT and verify
|
|
connectivity with the second DUT through the tunnel.
|
|
|
|
- Tunnel types: GRE, GRETAP, and VxLAN
|
|
- Connectivity: IPv4 and IPv6
