Modifying a Route
=================

Scenarios
---------

This section describes how to modify a custom route in a route table.

Notes and Constraints
---------------------

-  System routes cannot be modified.
-  When you create a VPC endpoint, VPN or Direct Connect connection, the default route table automatically delivers a route that cannot be deleted or modified.
