The Philadelphia Internet Exchange operates two BIRD route servers, both running on Ubuntu Linux, inside a VMware virtual environment. By utilizing virtual machines, we have the ability to migrate between VM hosts and minimize downtime due to hardware failures or maintenances. Each VM host has 40G connectivity directly to the peering switch, and a 1G management interface to our OOB switch.
The route servers do not forward any traffic and operate strictly on the control-plane.
We recommend participants establish a BGP session to each route server. The route servers do NOT peer with one another.
|Description||IPv4 Address||IPv6 Address||ASN|
|PhillyIX Route Server # 1||220.127.116.11||2001:504:90::1||54033|
|PhillyIX Route Server # 2||18.104.22.168||2001:504:90::2||54033|
Default Route Propagation
The default route is not permitted in the route servers and will be filtered.
RFC1918 Address Space
RFC1918 addresses, and other non-internet-routable address space, are NOT permitted in the route servers and will be filtered.
The route servers support the following community Strings. If no community is specified all accepted routes are forwarded to all peers.
|0:$PEERAS||Don’t announce route to RS peers with the ASN $PEERAS|
|54033:$PEERAS||Announce route ONLY to peers with the ASN $PEERAS|
|0:54033||Do not redistribute route to any peers.|
|54033:54033||Announce route to all peers (This is the default)|
