Hi,
I faced the similar problem before and if I remember correctly, OVS drops
the LLDP packets as the bridge mode in factions related to the STP
(Spanning Tree Protocol).
Sorry I forgot the detail for it, but the follow post seems to describe
some points.

Dear Yusuke,
The topology which i have created is comprised of only *OVSSwitch* class.
Now the *legacy nodes* which i have created have a *failmode attribute*
value of *standalone* and they are not connected to the controller. As per
the *tcpdump* used I noted that when the packet reaches from O
Hi,
What does "legacy node" exactly mean? Cisco switch or Linux machine?
As far as I know, some switches including Linux bridge do not transplant
LLDP packets for a loop prevention mechanism. Please confirm which switch
or node drops the packets first.
Thanks,
Iwase

Hi,
I have a query pertaining to *LLDP* (*ether-type = 0x88cc)*. When an
*OpenFlow* switch forwards *LLDP* packet to a *legacy node* why the legacy
node is unable to forward it. Is it because of non understanding of the
protocol or is it on account of *TTL *field in the LLDP frame.
Any help will

In peer.py file, PEER port number is hard coded to BGP Port Num.
peer_address = (self._neigh_conf.ip_address,
const.STD_BGP_SERVER_PORT_NUM)
I think, it can be configurable parameter from the API.

Hi Vidhu,
Ryu BGP Speaker does not have data-plane to forward packets. To implement
forwarding rules, Ryu supposes to connect to some OpenFlow switches or Linux IP
routing stack (like Zebra). So the approach to assign IP address to interface is
depending on how to realize data-plane with Ryu, I g

This means Ryu and other routers are connected with the iBGP(internal BGP)

Hi,
You mean modifying the rules of the BGP state transition (BGP FSM)?
You need to original rules?
Ryu maintains the FSM state at "ryu/services/protocols/bgp/peer.py",
so you can modify the rules if writing your code on it.
For example, Ryu will move on to ESTABLISHED state when received a KEE

You are starting gui_topology and tap app, which does not include topology
and OF APIs.
You need to start ryu.app.rest_topology and ryu.app.ofctl_rest for
/v1.0/topology/switches and /stats/switches respectively.

Hi Phani,
You seem to use tap.py (in sdnhub_apps), and it is not Ryu built-in module.
Do you use the SDN Hub VM image?
If so, how about contact with SDN Hub team?
