| 84 | The link type you select will affect the aggregates you are allowed to bind to in the next step. |
| 85 | <ul> |
| 86 | <li> <b>Stitched Ethernet</b> gives you a layer 2 link (e.g. a VLAN) between aggregates.</li> |
| 87 | <li> <b>EGRE Tunnel</b> gives you a layer 3 tunnel between aggregates.</li> |
| 88 | <li> However, if you would like a Layer 2 link connecting only ExoGENI sites, instead set the Link Type to "(any)" and pick any two ExoGENI aggregates except "ExoGENI ExoSM".</li> |
