Hi Iwase,
When i configure route_reflector, RYU BGP Speaker couldnt establish the
comminication with traditional bird router.
My code snippet is as below,
# code snippet
self.bgp_speaker = BGPSpeaker(64511, router_id,
ssh_console=True, ssh_port=4999,
ssh_host='localhost',
best_path_change_handler=self.best_path_change_handler )
self.bgp_speaker.neighbor_add(neighbor1_id, 64511,
is_route_reflector_client=True)
self.bgp_speaker.neighbor_add(neighbor2_id, 64511,
is_route_reflector_client=True)
self.bgp_speaker.prefix_add(prefix="10.2.1.0/24")
The error is(observed from wireshark trace),
Bird router closes the connection with UPDATE MESSAGE ERROR(3)/ Minor code:
Optional attribute Error(9)
In the bird log , i see the below error
Connection to peer 192.168.2.2 lost, reason: Peer closed connection
Resetting retry connect loop: True
Peer closed connectio
Note : If i just remove the "is_route_reflector_client=True" flag,
neighbor establishment and update happens.
Query1:
1. To enable route_reflector in RYU, Do i need to configuration any other
API or parameters?
Thanks
Suresh
