## Junos Base Configuration
-Here is a very simple base config below to allow SSH but I highly recommend you set up your own. Try configuring a Junos device once with some basic configuration then use that to create your own template. Remember this will apply to all out of the box devices that pull a DHCP address.

### Playing with hex
-Well in order to encode all of this info for DHCP option 43 we will need a hex converter to put it all together. The order we will combine them is as follows: `suboption` + `length` + `value`. This can be repeated for all suboptions you're configuring.

### Suboption 1
-Junos uses this suboption to set the config filename. For this example we will use suboption `1` + `9` + `init.conf`. Converting this to hex individually (with colon separators) becomes `01` + `09` + `69:6E:69:74:2E:63:6F:6E:66`

### Go the extra mile
If you have physical Junos devices you can also perform a software upgrade using ZTP. Suboptions 0 or 4 can be used to specify a software image for upgrades. Use the same steps as above to convert the suboptions and combine them.
