Hi everyone, Paolo,
I am trying to set up a Looking Glass server, everything works good, but
bgp multipath. Here is part of logs:

$
But Looking Glass always response with one prefix:
$ ./pmbgp.py -g -u pmacct -p <passwd>
b'{"results": 3, "query_type": 2}'
b'{"peer_ip_src": "10.X.X.X3", "peer_id": "10.X.X.X3", "peer_tcp_port":
65164, "peer_as": <AS>}'
b'{"peer_ip_src": "10.X.X.X2", "peer_id": "10.X.X.X2", "peer_tcp_port":
62339, "peer_as": <AS>}'
b'{"peer_ip_src": "10.X.X.X1", "peer_id": "10.X.X.X1", "peer_tcp_port":
50573, "peer_as": <AS>}'
$ ./pmbgp.py -a 91.233.216.0/24 -r 10.X.X.X1 -u pmacct -p <passwd>
b'{"results": 1, "query_type": 1}'
b'{"peer_ip_src": "10.X.X.X1", "peer_tcp_port": 50573, "event_type":

"bgp_nexthop": "<NH1>", "as_path": "<AS>", "comms": "<COMM>", "origin":

$
It's pmacct/pmbgp.py limitation or I missed something? Can anyone help me,
please?
