This is the most basic service that Internet Exchange Points provide. Internet Service Providers connect to TREX and sign up for Unicast Peering so that they can exchange their customers' traffic between each other.
Members can include this button or logo on their websites:
The VLAN can be requested in native form without any encapsulation in a port, or encapsulated with IEEE802.1q.
IPv4 addresses are assigned by TREX, but the IPv6 addresses on this VLAN are formed as follows:
- where ASN#
- This is the AS number of the router having this address, in hexadecimal. Examples: AS12345 becomes 3039 and AS1234 becomes 04D2.
- This is the router number, usually 0001, but if the member has more than one router this can be higher.
2001:07F8:001D:0004:0000:0000:72F8:0001or in a shorter format:
32-bit Autonomous Systems
Generating IPv6 addresses for 32-bit Autonomous System Numbers is very similar. The structure is:
- where ASHI
- This is the upper part or high 16 bits of the AS number.
- This is the lower part or low 16 bits of the AS number.
At this stage we are not restricting the use of MAC addresses on the shared medium, but we wish that members use the MAC addresses generated by the algorithm that follows. We are using the local OUI 0E-xx-xx on the shared medium:
0E:RN:AS:HI:AS:LOSo again, the first exchange point router would become:
