# INPUT FORMATS

- MRT routing table dump entries in TABLE_DUMP or TABLE_DUMP_V2 types
- Zebra/Quagga BGP records:
	- BGP messages (OPEN, UPDATE, NOTIFY, KEEPALIVE)
	- BGP state changes
- File may be gzipped or bzip2'd and/or passed in through stdin


The file format is described in the Internet Draft grow-mrt-13:
<https://tools.ietf.org/html/draft-ietf-grow-mrt-13>


# BUGS

If a single update message contains more than 8192 added or
withdrawn prefixes, all those above that number are ignored.

Files with a name longer than 999 characters cannot be processed.

The bgpdump program is not y2038 compliant. This is inherited from
the file format.


# DEBIAN

Besides bug fixes, the following changes were done in the packaging
for the Debian distribution:

- The maximum number of prefixes processed from a single update
    messages was raised from 2050 to 8192.
