Thanks Ben for your Reply ,This link is helpful for memory leak issues.
Could you please suggest How to debug if a vlib buffer leak is happening
inside some plugin.
Is there a way to print the content of the allocated vlib buffer ?

If you use the high level C API called vapi instead of the low level C
interface you may be in for an easier ride.

Hi Wei,
I suspect you wanted to register CREATE_LOOPBACK_REPLY instead of
CREATE_LOOPBACK in foreach_vpe_api_reply_msg

I used the following program to test API functions. For sw_interface_dump, I
got the reply with all the interfaces information, but for the create_loopback
message, I don't get any reply, although the loopback is successfully created.
I also tried ip_route_add_del, ip_route_add_del_v2, same
OK, so crash is clearly happening in DPDK code so you will need somebody
familiar with that driver to take a look.

Hoi,
Good to hear, Chunhui. Happy to hear you got this working without too much
trouble in the end!

Hi Buddy, thanks for reply, I already take account into the outbond issue
regarding two packets increments at one loop( if (is_send_syn && (1 <
n_left_to_next)) ). Actually, I couldn't find logical issue on source code. I
will read “l2-flood” node soure code for reference.

I think this should be taken care of by this test though.

It looks like it is a hardware issue on the pc2. I change the pc2 xl710
card and both the tcpdump and the ospfd now see the multicast hello packets
on the lcp loopback interface.

Hi,
You decrement/increment n_left_to_next/to_next twice in one iteration of the
loop, so you are writing out of bounds. Have a look at other nodes that do
packet copying like l2_flood.

You need to set loop5007 as the bvi for it to behave as a l3 interface instead
of l2:
set int l2 bridge loop5007 5007 bvi

You can track allocations with memory traces:
