And what to do with 4-byte AS-numbers then? That would explain the 8 bytes.
Looking futher: Two new attributes, AS4_PATH and AS4_AGGREGATOR, are introduced that can be used to propagate four-octet based AS path information cross BGP speakers that do not support the four-octet AS numbers. However this router is AS4 capable, but probably fails to understand a 4-byte AS in the normal AGGREGATOR attribute. If I understand correctly a AS4 capable router should understand when announcing that to it's peer. I'm I correct? Should I file this as a bug? (redback/ericsson is already looking also) regards, Igor
