Hi guys，
I’m testing the static arp.
When I configured one hundred thousand static arp ,and delete to 34467th, there
is a SIGABRT. More info is shown below:
VPP# set ip arp host-eth1 1.1.69.234 00:01:00:00:45:ea del
/home/vpp/build-data/../src/vnet/fib/ip4_fib.c:230 (ip4_fib_table_destroy)
assertion `0 == fib_table->ft_total_route_counts' fails
Program received signal SIGABRT, Aborted.

I doubt whether there is something remains in fib_table_entry, when we delete
the static arp.
for (ii = ARRAY_LEN(ip4_specials) - 1; ii >= 0; ii--)
{
fib_prefix_t prefix = ip4_specials[ii].ift_prefix;
prefix.fp_addr.ip4.data_u32 =
clib_host_to_net_u32(prefix.fp_addr.ip4.data_u32);
fib_table_entry_special_remove(fib_table->ft_index,
&prefix,
ip4_specials[ii].ift_source);
}
Is there any problem of the process?
Thanks,
Xyxue
