" If necessary, add your hosting router to the L3 agent on the new node. This example show how to add a hosting router named r1 to the L3 Agent using the UUID of 2d1c1dc1-d9d4-4fa9-b2c8-f29cd1a649d4: "

(overcloud) $ openstack network agent add router -l3 2d1c1dc1-d9d4-4fa9-b2c8-f29cd1a649d4 r1


(overcloud) [stack@undercloud-0 ~]$ openstack network agent add router -l3 efbb34e3-1426-416e-84ec-bce079b2a056  r1
usage: openstack network agent add router [-h] [--l3] <agent-id> <router>


so typo in '-l3' and should be '--l3'

(overcloud) [stack@undercloud-0 ~]$ openstack network agent add router --l3 efbb34e3-1426-416e-84ec-bce079b2a056  r1
(overcloud) [stack@undercloud-0 ~]$ echo $?
