To ensure that your connection to the INX is easy, as well as secure, we have created a set of templates for the configuration of various types of hardware in common use at the exchange point.

Although we do filter specific types of Layer-2 frames, we still encourage peers to keep their ports clean, and may insist on this before moving you out of quarantine.

Connection via a router

 We recommend that you use a Layer 3 device to connect to the INXes;  doing so, minimises your risk of creating any unnecessary loops.  Below are some configurations that should help if you connect directly to a router (preferred)

Classic IOS

Cisco IOS
interface <INT>
ip address 196.60.x.y

no cdp enable
no ip directed-broadcast
no mop enable
no keepalive 
no udld mode aggressive

Cisco XR
interface <INT>

interfaces {
    ge-0/0/0 {
        description "PEERING:: *INX”;
        unit 0 {
             family inet {
                 address 196.60.x.y/24;
            family inet6 {
                 address 2001:43f8:1fx::y/64


/interface ethernet set ether1 comment="PEERING:: *INX"
/ip neighbor discovery set ether1 discover=no
/ip address add interface=ether1 address=196.60.x.y/24
/ipv6 address add interface=ether1 address=2001:43f8:1fx::y/64 advertise=no
/tool romon port disable numbers=<Interfacenumber of Ethernet>

Connecting via a switch

In general it's always safest to connect to an Internet Exchange Point onto a layer-3 router port.  However, we understand that sometimes this is difficult to do.  In cases where you need to connect your INX port onto a switch, you will want to pay particular attention to making sure that the port that the IX cross-connect terminates on, has been secured.  Below are templates that should help you make a secure connection to the INX.


vtp mode transparent
no spanning-tree vlan 9999
