You do not need an axi2axi connector for the axi pcie bridge to work.  In fact, I've had many systems without the connector.  The axi2axi connector is only used if you need a master to access registers that are on a different interconnect than its own.

 

If you want to see some examples with the pcie bridge, take a look at the following ARs:

Hope this helps.

It is not needed, but it will depend on your system.  If you look at your system and you realize that you need to access a peripheral on another AXI interconnect than you're currently mastering on, then you'll need to add the connector.
