Hi, You can reorder the route and ABF programming as a work around. I’ll have a fix shortly.

These are the steps to generate the problem: First setup interfaces: vppctl set int state GigabitEthernet3/0/0 up vppctl set int state GigabitEthernet4/0/0 up vppctl set int ip address GigabitEthernet3/0/0 200.200.200.2/24 vppctl set int ip address GigabitEthernet4/0/0 100.100.100.1/24 Now create an acl using vpp_api_test acl_add_replace permit dst 1.1.1.1 And then add abf policy and route which cause crash vppctl abf policy add id 9001 acl 0 via 100.100.100.2 GigabitEthernet4/0/0 vppctl abf attach ip4 policy 9001 priority 1 GigabitEthernet3/0/0 vppctl ip route add 8.8.8.0/24 via 100.100.100.2 GigabitEthernet4/0/0 I see this SIGSEGV on both master and stable/1904 branches: received signal SIGSEGV, PC 0x7f51a1b60160, faulting address 0x7f61608d8814 #0 0x00007f51a0fde0db 0x7f51a0fde0db #1 0x00007f51a0904890 0x7f51a0904890 #2 0x00007f51a1b60160 fib_urpf_list_lock + 0x10 #3 0x00007f51a1b5408f fib_entry_src_mk_lb + 0x1bf #4 0x00007f51a1b54391 fib_entry_src_action_install + 0x131 #5 0x00007f51a1b51691 fib_entry_create + 0x71 #6 0x00007f51a1b486b8 fib_table_entry_update + 0x1c8 #7 0x00007f51a1b6398e fib_api_route_add_del + 0x7e #8 0x00007f51a1879e3f vl_api_ip_route_add_del_t_handler + 0x21f #9 0x00007f51a1f26d8c vl_msg_api_handler_with_vm_node + 0x8c #10 0x00007f51a1f0b815 vl_mem_api_handle_msg_main + 0x45 #11 0x00007f51a1f1b38d 0x7f51a1f1b38d #12 0x00007f51a0f92ea6 0x7f51a0f92ea6 #13 0x00007f51a04818bc 0x7f51a04818bc What should I do to solve this problem?
