Help with decoding BGP version 3 & 4.

[Sennen Carlos <[e-mail]>]

Hi,

I work at Network General Corp., the Sniffer company and am in the
protocol interpreter group. I'm current working on upgrading BGP
version 2 decodes to versions 3 & 4 but have run into a problem.

Open, Update and Notification types have changed from the original
version 2.  Since we should be able to decode all three versions I
have to be able to tell which one is which by looking at the packet.
`Open' is easy since it has the version number as a parameter but the
other two types, Update and Notification are almost impossible to
figure out. I was wondering if someone out there has run into a
similar problem and could assist me.

Some trace files would also be helpful as I am working out of the
RFC's and haven't seen any real BGP traffic data yet.

Thanks,

Sennen.
