Of the fall-2011 projected and planned upgrades:

Additional capacity between exchange point routers and backbone/ 
aggregation devices in Chicago and Virginia areas were complete in  
early January.  Two 10GE links in each city; are now providing the  
head-room needed to move forward the migration of participant  
connectors to the integrated network.

For reference the following URL shows links that are connecting  
exchange point sites together:

A southern cross-county link is pending in January as our Internet2  
engineers continue to work toward that.

Additional capacity in the NY-Chicago-Virginia triangle was slated to  
be brought online via the BTOP optical transport.  Of those One link  
between New York and Virginia was completed some weeks ago.  Two  
Chicago - Virginia links had been recently set for completion last  
week, but is not yet online.

Exchange port upgrades pending:
-- One additional Ashburn Exchange port to be moved to integrated  
network on Jan. 20th.
-- Additional exchange point connections pending in: Ashburn, Chicago,

Interface graphing (via SNAPP) had been pending tools alteration to  
support redacting specific peer facing interfaces.  This is to adhere  
to expectations and mutual agreement by a handful of 3rd party  
networks, though that is the exception rather than the norm where  
generally interface usage should be visible.  The software changes to  
support this are believed to be mostly sorted and will see NOC  
activity in the coming weeks.


> 5.   BGP Community Tags

Following up on topic from past meetings about announcement control to/ 
from commercial networks attached to the R&E RIB and to affirm  
direction before NOC implements those improvements.  The two items  
with broad support were noted as:

Per-ASN announcement controls (toward commerical non-members/ Net+ and  
other commerical):
        • 65000:<ASN> Do not advertise at all to the peer ASN
        • 65001:<ASN> Prepend once toward peer ASN
        • 65002:<ASN> Prepend twice toward peer ASN
        • 65003:<ASN> Prepend thrice toward peer ASN
	• 65009:<ASN> Allow advertisement toward peer ASN if otherwise  
excluded by more general community control (e.g. 11537:2002)

Per commercial-network opt-out:
(existing) 11537:2002 - Block prefix to commercial R&E peers
Replicate the above for other commerical groups as they may arise  
(e.g. Net+)
