Subject: [vpp-dev] Need help on GRE tunnel. #vpp #vpp-dev
All,
I am trying to ping from VPP to another VM in which GRE tunnel is formed.
I am seeing below error , after executing
show error. cli.
40null-node blackholed packets
Can you please help me to resolve this issue?
Here,
vpp# show gre tunnel
[0] instance 0 src 50.50.50.50 dst 60.60.60.60 fib-idx 0 sw-if-idx 18 payload
L3 point-to-point
Here fib-idx 0 is chosen by default.
When for pinging i am using the below command.
ping 60.60.60.60 source VirtualFuncEthernet0/6/0.900
Here GRE tunnel has fid-idx 0 and
VirtualFuncEthernet0/6/0.900 (up): has
L3 20.20.146.226/24 ip4 table-id 1 fib-idx 1
Show ip fib shows

Is this correct config?
Can any one please shed some light on this?
Thanks in advance.
