How to choose a RD and RT scheme
General form
- <ASN>:ថ bit number> or <IP address>:ក bit number>
Use officially assigned ASN or IP addresses
We use ASN as this makes the scheme independent of the physical layout
Scheme for RD is quite simple
Requirement: RD should be unique
- <own ASN>:ថ bit sequence number, starting with 1000>
- needs a central database for sequence numbers
- Excel sheet, or some clever router config tool
- One could think that it would be easier to use the <IP>:<number> form
- use router loopback address
- make sequence number unique per router
- what happens when you move a customer to another box?
