Comment 0 for bug 1742450

in the page of https://docs.openstack.org/neutron/pike/admin/fwaas-v2-scenario.html,the current configuration of file l3_agent.ini will cause some error in l3_agent.log.

Version:pike
Linux version 3.10.0-693.11.6.el7.x86_64 (<email address hidden>) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Thu Jan 4 01:06:37 UTC 2018

following is the detail and the fix way:

WRONG:
     [AGENT]
     extensions = fwaas

RIGHT:
     [AGENT]
     extensions = fwaas_v2

if it was configured to "fwaas" in Firewall-as-a-Service (FWaaS) v2 scenario, there will be error in l3_agent.log :
