[GROW] comment for draft-ietf-grow-bmp-00

[kura at iij.ad.jp]

Hello,

I have a comment for draft-ietf-grow-bmp-00. It is about adding a
bit flag to Peer Flags field in BMP common header. 

The new bit is used in order to indicate whether AS numbers (ASNs)
in AS_PATH (and AGGREGATOR) attribute, which must be included in
Route Monitoring messages, are 4-octet or 2-octet. I think the
information of ASN size will be needed on monitoring stations when
parsing BGP UPDATE PDUs.
 
Regards,
