end

#create ⇒ Object

This function will first add bds to the system bridge-domain and then create the bds. If bds already existing then just create. Else add the non added bds to system range first then create all. This is to avoid the idempotency issue as system add command throws error if a bd is already present in the system range.

#default_bd_name ⇒ Object

This default getter is a bit different them most. When a brige-domain gets created it gets a default name assigned that follows the pattern ‘Bridge-DomainX’ where X is the bridge domain id (@bd_ids).
