Hi Ravi,
By default, vcl relies on the binary api to attach to the session layer in vpp.
It is possible to initialize another binary api connection from your app, apart
from the one transparently created by vcl, but it requires some careful
non-default initialization of a series of data structures.
So the simplest thing would be to use the new api exposed by the session layer.
For that, in vpp’s startup.conf add “session { use-app-socket-api }” and in
vcl.conf add "app-socket-api /var/run/vpp/app_ns_sockets/default”.
Note that this is a recent addition so it’s only available on vpp master.
Regards,
Florin
