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.
Crash Dump:
