Layer3 “PacketNet”
• Review architecture, connection methods
• Current status– Members– Peer networks– Institutions connecting through members
• ‘Advanced technologies’
• User-influenced policies
Typical Member Connection
Routed IP Service• Production-quality, no explicit SLA
• AUP-free– no prefix size limit (/32s accepted)– Still use prefix-lists or AS-path lists for case of
misconfiguration
Local Prefs
• Member default:– primary 10G: 500– backup 1G: 450– community-driven: 200, 400, 500, or
600
• Others:– peers: 300
Communities• “Type” Communities (set by NLR)• Other Communities (set by member)
– Blackhole– Local Pref setting– AS-prepend– “do not send to...”– members-only– See communities page at
http://noc.nlr.net/l2_l3_doc/nlr-communities2.html
PacketNet Services
• Jumbo frames (9000 IP MTU)• IPv4
– Unicast
– Multicast (MSDP, PIM, MBGP NLRI)
• IPv6– Address allocations available if needed
– Unicast
– Multicast (PIM, MBGP, Embedded RP)
Services (basic and advanced)
• What are members actually doing?• See http://noc.nlr.net/l2_l3_doc/member_table-advanced.html
