NDB MPLS Not working

[svenauhagen]

Hi,

I am on the latest 0.7.9 release and I can not query any MPLS routes. IPRoute gets them just fine:

>>> ipr = IPRoute()
>>> ipr.route('show', family=AF_MPLS)
({'family': 28, 'dst_len': 20, 'src_len': 0, 'tos': 0, 'table': 254, 'proto': 4, 'scope': 0, 'type': 1, 'flags': 0, 'attrs': [('RTA_DST', [{'label': 110, 'tc': 0, 'bos': 1, 'ttl': 0}]), ('RTA_NEWDST', [{'label': 200, 'tc': 0, 'bos': 1, 'ttl': 0}]), ('RTA_VIA', {'family': 2, 'addr': '192.168.10.1'}), ('RTA_OIF', 5)], 'header': {'length': 64, 'type': 24, 'flags': 2, 'sequence_number': 255, 'pid': 4185219065, 'error': None, 'target': 'localhost', 'stats': Stats(qsize=0, delta=0, delay=0)}, 'event': 'RTM_NEWROUTE'}, {'family': 28, 'dst_len': 20, 'src_len': 0, 'tos': 0, 'table': 254, 'proto': 4, 'scope': 0, 'type': 1, 'flags': 0, 'attrs': [('RTA_DST', [{'label': 200, 'tc': 0, 'bos': 1, 'ttl': 0}]), ('RTA_VIA', {'family': 2, 'addr': '192.168.10.1'}), ('RTA_OIF', 5)], 'header': {'length': 56, 'type': 24, 'flags': 2, 'sequence_number': 255, 'pid': 4185219065, 'error': None, 'target': 'localhost', 'stats': Stats(qsize=0, delta=0, delay=0)}, 'event': 'RTM_NEWROUTE'})

Here are the actual routes in my system:

ip -f mpls r s 110 as to 200 via inet 192.168.10.1 dev eno0 proto static 200 via inet 192.168.10.1 dev eno0 proto static

Anything I can try out or debug on my end to find out the problem?

Best and thanks Sven

I found the problem, the initial dump is not including MPLS routes. I just sent a PR for it.

Thanks!
