Modifying a Route

Scenarios

You can modify an existing route in a route table.

If a route table is associated with a subnet, modifying rules in the route table may affect how and where traffic is directed. Be careful with this operation as it may interrupt services.

Notes and Constraints

• System routes cannot be modified.
• When you create a VPN, Cloud Connect, or Direct Connect connection, the default route table automatically delivers a route that cannot be deleted or modified.
• Routes with the next hop type of cloud container cannot be modified or deleted.
• Routes with the next hop type of VPC endpoint cannot be modified or deleted.
