bgp update destroying transit on redback routers ?

Hi all,

A new update. A coder from ericsson told me that the problem is not
4-byte asn related. It is related to aggregator-asn=0 and
aggregator-ip=0.0.0.0. Ericsson does not accept this as valid ASN and
IP-address.

The question is now, are all other vendors wrong in accepting this
attribute (clearly ASN=0 and IP=0.0.0.0 isn't corresponding to the RFC
stating 'which shall contain its own AS number and IP address') or is
Ericsson being to strict?

regards, Igor
