Hi Florin，
After starting VPP, I just configured two commands, first is "lisp enable on",
another command(not congfig in vpp CLI) is to directly pass parameter
parameters to vl_api_gpe_add_del_fwd_entry_t_handler. This problem exists every
time in the 18.01 version of VPP
Breakpoint 1, vl_api_gpe_add_del_fwd_entry_t_handler (mp=0x2b8413872f9c) at
/home/vpp/17.07_x64/vpp/build-data/../src/vnet/lisp-gpe/lisp_gpe_api.c:328
328 {
(gdb) p *mp
$1 = {_vl_msg_id = 16129, client_index = 805306625, context = 0, is_add = 1
'\001', eid_type = 0 '\000', rmt_eid =
"1.1.3.1\000\000\000\000\000\000\000\000",
lcl_eid = "1.1.2.1\000\000\000\000\000\000\000\000", rmt_len = 24 '\030',
lcl_len = 24 '\030', vni = 16777216, dp_table = 16777216, action = 4 '\004',
loc_num = 33554432,
locs = 0x2b8413872fd7}

Thanks,

Hi Xyxue,
Did you by chance configure an ip or a route through the gpe interface? If yes,
then that is probably the issue. If not, could you provide more details
regarding your configuration.
Thanks,
Florin

Hi guys，
There is an assertion when I was configuring the GPE service, and I didn't find
a solution. Can you help me see the reasons for it?
