Hi Iwase,
Thanks for getting back to me.
I have tried some of your suggestions, but still doesn't seem to be able to
connect to the API.
*My config files look like this:*
! OSPF configuration for r3
!
hostname r3
password zebra
!
router ospf
passive-interface r3-eth0
network 10.0.3.0/24 area 0.0.0.0
network 10.1.100.0/24 area 0.0.0.0
!
log stdout
*and*
! Configuration for zebra (NB: it is the same for all routers)
!
hostname zebra
password zebra
log stdout
*I have been running the example with this command, but also tried
different ports (2600, 2601, 2604):*
$ sudo ryu-manager sample_dumper.py --verbose --zapi-router-id 10.1.100.3
--zapi-server-host /var/run/quagga/zebrar3.api --zapi-server-port 2600

open:*
$ netstat -nltp

I hope this info may clarify a couple of things.
Thanks.
