Hi Bhanu,
Sorry, then I’m out of ideas. And I don’t have access to similar HW to try and
reproduce and debug. A var args issue is still my best guess.

Hi Neale,
Please find the information below,
ARCH = aarch64
OS = Ubuntu 16.04
GCC = Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4
I am using VPP stable/1704 and external DPDK version 17.02.
I will test as you suggested and would let you know.

Hi Bhanu,
Can you give us some information on the CPU arch, OS and compiler version you
are using please.
My best guess at the issue here is the problem of integer promotion through a
variadic function. Perhaps you could test this idea by declaring;
int fproto = FIB_PROTOCOL_IP4;
And then pass the variable ‘fproto’ and not FIB_PROTOCOL_IP4 to the call to
vlib_cli_output (in frame 4).

Set a breakpoint in format_fib_table_name, and see if e.g. fib_table->ft_desc
is NULL.

Subject: [vpp-dev] VPP 1704 and router plugin
Hi All,
We are building router plugin with VPP 1704 branch. We used VPP stable/1704
branch and vppsb source code after (https://gerrit.fd.io/r/#/c/5881/ ) check in.
Router plugin is loaded properly. We are able to see the router plugin when
“vppctl show plugin” command is issued.
But, VPP daemon is getting crashed when we issue “vppctl show ip fib”. Crash
dump and the VPP configuration is given below.
Please help me in resolving this issue.
