I will try to create a PR in doc-sle providing some examples.

It seems extrapara is not documented and basically it is the routes 5th field
(extra options)

https://documentation.suse.com/sles/15-SP2/html/SLES-all/cha-network.html#sec-network-yast-change-route

Example:

<route>
  <destination>default</destination>
  <name>eth0</name>
  <gateway>192.168.1.1</gateway>
  <extrapara>table 100 metric 150</extrapara>
</route>
