SGIX operates 2 route-servers (RS) in Singapore. Once peered with the RS, there is no need to maintain multiple BGP sessions with other members.

 

Please note the following when peering with RS

  1. Remove private ASN in the prefix advertisement
  2. Prefixes stated in RFC 1918 should be removed.
  3. Disable check on first-ASN. This may be applicable to Huawei (“undo check-first-as”) and Cisco equipment (“no bgp enforce-first-as”)
  4. RS accepts a maximum of 2,000 prefixes by default.

Conditions

  1. Members are advised to peer with both route servers.
  2. Members can choose to establish or maintain bi-lateral peering arrangement with other members.
  3. Members agree not to hold SGIX responsible for any impact on traffic flow due to policies request configured at RS by other members.

 

 

BGP Communities

SGIX route-servers support BGP community attributes. Besides the standard well-known community attributes like NO_EXPORT and NO_ADVERTISE, the following table shows other supported attributes and the top-down evaluation order.

0:55518 Block announcement of prefixes to all peers
0:peer-as Block announcement of prefixes to peer-as
55518:peer-as Advertise to peer-as only

 

 

Prefixes which are untagged will be advertised to all route server peers. Attributes that do not match SGIX’s attributes will be passed on transparently.

For members having 4-byte ASN, they will be mapped to private ASNs. Hence, prefixes announcement are still possible to be manipulated using community strings.
