L1 ConstructAWS::EC2::RouteServer

CfnRouteServer

Specifies a route server to manage dynamic routing in a VPC. Amazon VPC Route Server simplifies routing for traffic between workloads that are deployed within a VPC and its internet gateways. With this feature, VPC Route Server dynamically updates VPC and internet gateway route tables with your preferred routes to achieve routing fault tolerance for those workloads. This enables you to automatically reroute traffic within a VPC, which increases the manageability of VPC routing and interoperability with third-party workloads. For more information see [Dynamic routing in your VPC with VPC Route Server](https://docs.aws.amazon.com/vpc/latest/userguide/dynamic-routing-route-server.html) in the *Amazon VPC User Guide* .

Import

import { CfnRouteServer } from 'aws-cdk-lib/aws-ec2';

Or use the module namespace:

import * as ec2 from 'aws-cdk-lib/aws-ec2';
// ec2.CfnRouteServer

Properties

Configuration passed to the constructor as CfnRouteServerProps.

amazonSideAsnRequired
number

The Border Gateway Protocol (BGP) Autonomous System Number (ASN) for the appliance. Valid values are from 1 to 4294967295. We recommend using a private ASN in the 64512–65534 (16-bit ASN) or 4200000000–4294967294 (32-bit ASN) range.

persistRoutesOptional
string

Indicates whether routes should be persisted after all BGP sessions are terminated.

persistRoutesDurationOptional
number

The number of minutes a route server will wait after BGP is re-established to unpersist the routes in the FIB and RIB. Value must be in the range of 1-5. The default value is 1. Only valid if `persistRoutesState` is 'enabled'. If you set the duration to 1 minute, then when your network appliance re-establishes BGP with route server, it has 1 minute to relearn it's adjacent network and advertise those routes to route server before route server resumes normal functionality. In most cases, 1 minute is probably sufficient. If, however, you have concerns that your BGP network may not be capable of fully re-establishing and re-learning everything in 1 minute, you can increase the duration up to 5 minutes.

snsNotificationsEnabledOptional
boolean | IResolvable

Indicates whether SNS notifications are enabled for the route server. Enabling SNS notifications persists BGP status changes to an SNS topic provisioned by AWS .

tagsOptional
CfnTag[]

Any tags assigned to the route server.
