Hi,
We have a question about the nox discovery.
Our NOX version is NOX 0.9.0(zaku) in our openflow enviroment.
We monitor a port of a openflow by wireshark, and we observe that the
lldp packets are sent to a multicast MAC (01:23:00:00:00:01).
However we see the discovery.py code and find
Right. Someone correct me if I am wrong here, but really the only difference
between OFDP and normal LLDP is that OFDP uses a normal multicast address so
that it can see connectivity across non-OpenFlow switches.
The purpose being... if you have two OpenFlow switches connected via an
I believe OFDP uses LLDP as Kyriakos mentioned. So, there is no real
difference here.
As for the question of discovering a link between two OpenFlow
switches connected by a non-OpenFlow switch, the link will be
discovered if the switch does not process LLDP and thus pass it on.
Else, the
Oops.. I read the GENI document again, and Murphy is right in that the
multicast address is different here. My apologies.
This address will be forwarded by mac bridges though. Won't this be
risking a broadcast storm? Am I missing something again?

So the normal LLDP multicast address should never be forwarded. No problem
there except that NOX couldn't see through intermediate switches there.
On the other hand, with the OFDP address... OpenFlow switches still won't
forward such messages (NOX looks at them in discovery, but never
Exactly, this version is what would make sense to me too :
(And I also doubt NOX currently does what the page claims)
