Description

Once a VPC peering connection is established, routing tables must be updated to establish any connections between the peered VPCs. These routes can be as specific as desired, even peering a VPC to only a single host on the other side of the connection.

Remediation

From Console

1. Logon to VPC console.
2. Open the routing table.
3. Remove and add route table entries to ensure that the least number of subnets or hosts as is required to accomplish the purpose for peering are routable.
