Physical setup

Overview

SGIX switching fabric (Fabric) is at 2 Point-of-Presences (PoPs) – 1-Net and Global Switch. Currently, the 2 PoPs are interconnected via a 2G. This is done by link aggregating 2 x 1G circuit. Utilization of this inter-PoP link will be made available online to members.

Switchport Configuration

By default, all our switchports are configured to permit only 2 MAC address per port and are in trunked mode. In additional, the switchport will goes into errdisable mode if BPDU packets are detected. If your equipment is a switch, please let us know during the provisioning process.

To avoid performance issue, please hardcode the speed and duplex of your router port that is connected to Fabric.

Logical setup

IPv4 and IPv6 Peering

For trending the growth of IPv4 and IPv6 traffic, the peering for IPv4 and IPv6 is split into 2 VLANs. Members should consider doing VLAN tagging (IEEE 802.1q) on their router interface in the initial setup, this will avoid downtime should you choose to do IPv6 peering in the future. If you prefer just to do IPv4 peering only, please let us know during service provisioning.

Multicast peering

For multicast peering, members are able to do it over the IPv4 peering VLAN.

Closed group peering/transit services

We offer a non-penalty basis Service level target of 99.5% (monthly basis) hence transit arrangement over the peering switch is discouraged. For closed group peering /transit services, please cater your own address to number the routers interfaces.
