Re: 32 bits ASN on Cisco

[Paolo Lucente <pl+list () pmacct net>]

The reference to a IOS supporting 32-bit ASNs being too fresh
was specific to the 7600 platform and the SRE software train.

As of SRE1, for example, NetFlow v9 template still advertizes
source and destination ASNs fields as 2 bytes long.

Cheers,
Paolo
