[Ryu-devel] lldp not working if there exist legacy switch in topology

[Yi T. <a86...@gm...>]

Hi

As title, my topology looks like:

h1 - s1 - [legacy switch] - s2 - h2

h1 can ping h2 (simple_switch works fine)

but I can't find any links by using restful api(rest_topology)

I think there should be a link (s1 <-> s2) in topology because legacy
switch should let lldp packet pass

My env:
mininet 2.2.1 with ovs 2.0.2
switch use OpenFlow version 1.0
ryu version: b5c4b9a (last git commit)

ryu command:
ryu-manager --observe-links ryu.app.rest_topology ryu.app.simple_switch

mininet script:
