[rbak-nsp] SE600 BGP Session drops

[David Freedman]

Hey Florian,

My Online BGP decoder tool at http://bgpaste.convergence.cx/ makes easy
work of this (providing you fix the line break problem)

PREFIX: 89.31.48.0/24

AS_PATH: 6939 6762 3269 20746 (Origin is "ASN-IDC IT Telecom S.p.A.")


but actually, your problem is here:

Type code: AGGREGATOR (7) : 07
Length: 8 bytes : 08
Aggregator AS: 0 : 00000000
Aggregator origin: 0.0.0.0 (0.0.0.0) : 00000000


Its complaining about this AS0 aggregator, this is a known SEOS issue and
is related to some unclassified behaviour in original BGP standards which
is in the process of being rectified (*)

The session reset behaviour is also wrong and is currently also being
addressed (**).

I'm sure the appropriate SEOS people can follow up (either on-list or
through your account team) to tell you what is planned for the s/w.

Dave.
