General Status
• NOC is staffed by VeriLAN, volunteers and Comcast
• IPv6 across all announced wireless and wired networks
• All meeting areas have wireless, as does JW’s Restaurant
• SSID ietf-v6ONLY is exactly that
Wireless• New AIR-1252 a/b/g/n access points donated by Cisco
- New access points have compatibility problems with 802.11b clients
- Fixed by deploying AIR-1131 access points, no fix for the AIR-1252s yet
• Service available in 3rd, 4th and 5th floor meeting rooms, Franklin Ballroom Lounge and JW’s restaurant.
• Lots of Wireless SSIDs– ietf (a/b/g)– ietf.1x (a/b/g)– ietf-a (a only)– ietf-a.1x (a only)
– ietf-v6ONLY (a/b/g) [no IPv4]
Upstream Connectivity
• “100Gb” ethernet in building from Comcast. 8 x 10Gb into a single lambda to McLean, VA (AS 7922)
• 10Gb ethernet in building from Comcast on same fiber, different lambda, different termination (Philadelphia), same AS
• 100Mb backup wireless link to Comcast Center (AS 36733)• Native Comcast IPv6 connectivity
– Comcast peers with ISC and Global Crossing
• Backup IPv6 tunnel to ISC (down for now as native is good)• Peaking around 45Mb inbound / 30Mb outbound
What we had to do to make IPv6 work:
Routing was non trivial for a simple multi-homed setup- “100Gb” line complicates setup as it presents as 8 x 10Gb interfaces with a single ebgp-multihop session and eight point to point static routes- 10 BGP peerings, 6 specifically for IPv6- Used tunnels in the beginning as native routing needed extensive work to ensure reachability. After many hours of work from Comcast and their peers we were able to go completely native.- HSRP couldn’t save us on IPv6 so devices using RA from backup didn’t always go the right way
Statefull DHCPv6 is running and issuing leases. Fairly simple to do(configure, make, make install and a simple config script worked)
DNS, SMTP and NTP servers had to be configured to listen on IPv6 interfaces
Management over IPv6 is still problematic, so a pure IPv6 network is still tricky to operate
