Hi!
I think fast-failover in s1 was succeeded.
But, for the packet from h2 to h1,
s4 may send it to s2, because s4 cannot notice the link between s1 and
s2 is down.
So, the packet from h2 to h1 is dropped in s2, and ping failed.
To avoid this, how about you have a link between s2 and s3?
And put a fast-failover action to s2 so that s2 send packets to s3 if
the link between s1 and s2 is down.
It can be said for s5, too.
Thanks,
Fujimoto

Hi,
I am trying to use mininet to test my fast failover app.
(with Openflow 1.3, Open vSwitch 2.6.1)
My testing topology is shown as follow.
/ 2 \ / 5 \
h1 - 1 4 7 - h2
\ 3 / \ 6 /
It is fine when I using mininet to pingall.
(The path is *s1-s2-s4-s5-s7*)
But if I using mininet with command *_link s1 s2 down_*
I think it should trigger the ff and reroute from s1-s2 to s1-s3
However, it's not.
(I pretty sure the rule is matched and go to the group table,
dl_dst=00:00:00:00:00:02 actions=group:2)
The following is my group table in s1.
group_id=2,type=ff,
bucket=watch_port:2,watch_group:2,actions=output:2,
bucket=watch_port:3,watch_group:2,actions=output:3
group_id=1,type=ff,
bucket=watch_port:1,watch_group:1,actions=output:1
How should I deal with it?
Is mininet should set some options?
Thanks for your help.
I truly appreciate it.
Rex.
