Hi,
In the current git version an offset error exists in the dissection of a BGP
update regarding the community path attributes. This leads to an incorrect
decoding of the value of the BGP communities.
A quick check with the sample bgp capture:
http://wiki.wireshark.org/SampleCaptures?action="">
When we decode manually the packet capture, the BGP Update (packet #17) has two
BGP communities:
- fe 09 01 f4 => 65033:500
- fe 09 02 58 => 65033:600
But the BGP packet dissector shows:
I joined a quick path to fix this issue.
Regards,
Yann.
