Adding Routes to a Route Table

Scenarios

Each route table comes with a default route, which is used to allow instances in a subnet to access public services on the cloud or different subnets in a VPC to communicate with each other. You can also add custom routes as required to control traffic routing.

Notes and Constraints

• Generally, the destination of a custom route cannot overlap with that of a local route. The destination of a local route can be a subnet CIDR block and CIDR blocks that are used for internal communications.
• You cannot add two routes with the same destination to a VPC route table even if their next hop types are different.

For example, an IP address group cannot contain 192.168.0.1-192.168.0.62. You need to change 192.168.0.1-192.168.0.62 to 192.168.0.0/26.	IPv4: 192.168.0.0/16
   Next Hop Type	Mandatory Set the type of the next hop. NOTE: When you add or modify a custom route in a default route table, the next hop type of the route cannot be set to VPN gateway, Direct Connect gateway, or Cloud connection.	VPC peering connection
