Large 32-Bit AS-Numbers are displayed negative, i.e. 4294901906 is displayed as -65390
those numbers may be invalid, but as they are contained in the RIPE RIS dump, they could be displayed correctly.

Fatal error: exception Types.SubError("len: 0 - start: -2 - end: 2")

If I call mabo without the mrt file as an argument I get this error, which is a bit weird.

Hi @guedou @nv-anssi ,

I am unable to parse the BGP MRT update files collected from openbgpd router.
bgp command used to generate the update files dump all in "/tmp/all-in-%H%M" 300

It parses few records, then fails with below error

MRT parsing error: MRT dump is truncated: 1492578098 16/4 99
MRT parsing error: MRT dump is truncated: 1492578098 16/4 99
MRT parsing error: MRT dump is truncated: 1492578098 16/4 99
MRT parsing error: MRT dump is truncated: 1492578098 16/4 99

I am able to parse the RIB files from the same router, problem is with update files.

But I am able to parse the mrt files from RIPE.

Thank you

Can support for TABLE_DUMP be added?

Example file: http://instituut.net/~job/ribs.20080913.0000.bz2

using the example data http://data.ris.ripe.net/rrc01/2016.01/bview.20160101.0000.gz
I executed the mabo prefixes with three versions of the file

• plain bview.20160101.0000
• gzip bview.20160101.0000.gz
• bzip2 bview.20160101.0000.bz2

The first two work fine, using mabo on a bzip2 compressed file reports no prefixes?
I'm using Ubuntu 18.04 as the host OS.
