CoRE Resource Directory: Simple Endpoint Example
================================================
This example shows how a node can register with a CoRE resource directory using
the simple registration procedure as described in
draft-ietf-core-resource-directory-15, section 5.3.1.
When running this example, you **must** define the RD server's IPv6 address
statically, using the `RD_ADDR` environment variable:
```
RD_ADDR=\\\"abc:0815::123\\\" make all
```
Per default, this is set to some random global address (`affe::1`) for compile
test reasons. So change it!
Additionally, you can change the RD server's port by overriding the `RD_PORT`
variable:
```
RD_ADDR=\\\"affe::bee\\\" RD_PORT=12345 make all
```
The registration lifetime is set for demonstration purposes to a rather short
time of 60s in this example. You can easily override that value using the
`RD_LT` variable:
```
RD_ADDR=\\\"abc::def\\\" RD_LT=3600 make all ...
```
