FL-IX offers services on the following physical media:
- 10GE LR over SMF
- 100GE LR4 over SMF
By announcing their routes to the route servers, members can begin immediately exchanging traffic with other route server participants without configuring individual BGP sessions.
Members who wish to connect to the route servers should disable enforce-first-as on the route server BGP sessions.
The route servers are:
By default, all routes advertised by members to the route server are sent to all other members. Members who wish to control distribution of their routes may do so using these BGP communities:
In order to control distribution of routes to members with 4-byte ASNs, you must choose large communities, but must use either standard (16-bit) or large (32-bit) communities exclusively and not mix the two.
For standard communities:
|Prevent announcement of a route to a specific peer||0:peer-asn|
|Announce a route to a specific peer||63221:peer-asn|
|Prevent announcement of a route to all peers||0:63221|
|Announce a route to all peers||63221:63221|
For example, a route with the standard communities 0:63221, 63221:64501, and 63221:64502 would be sent only to route server peers with ASNs 64501 or 64502.
For large communities:
|Prevent announcement of a route to a specific peer||63221:0:peer-asn|
|Announce a route to a specific peer||63221:1:peer-asn|
|Prevent announcement of a route to all peers||63221:0:0|
|Announce a route to all peers||63221:1:0|
For example, a route with the large communities 63221:0:0, 63221:1:64501, and 63221:1:64502 would be sent only to route server peers with ASNs 64501 or 64502.
FL-IX implements MAC filtering using layer 2 access control lists to protect the infrastructure against loops. Members who intend to swap routers or otherwise change their MAC address should coordinate this change in advance with the FL-IX NOC. In the event of an after-hours emergency necessitating a MAC change, members should contact the FL-IX NOC for assistance.
FL-IX will accept and forward from member ports traffic with Ethertypes of:
- 0x0800 IPv4
- 0x86dd IPv6
- 0x0806 ARP
