Hi Ole,
Yea, i have my routes on the "show ip6 fib", but still even ping did not
work.
I tried to ping the ips assigned to the local ports on vpp, -> did not work
tried ip4, still did not work.
I could not figure out what "Configuration" i am missing here.
Outputs :
vpp# sh interfaces
Name Idx State Counter
Count
FortyGigabitEthernet2/0/0 1 up
FortyGigabitEthernet4/0/0 2 up
local0 0 down
