    String

    No

    Yes

    The description of the routing policy.

    None.

    SourceInstanceIdsReverseMatch

    Boolean

    No

    Yes

    String

    Yes

    No

    The direction in which the routing policy is applied.

    Valid values:

    You can specify up to 32 communities.

    A community must comply with the Request for Comments (RFC) 1997 standard. The RFC 8092 standard that defines Border Gateway Protocol (BGP) large communities is not supported.

    Note

    If the configurations of communities are invalid, routes may not be advertised to data centers.

    DestinationInstanceIdsReverseMatch

    Boolean

    No

    Yes

    Specifies whether the match is successful if the destination instance IDs are not in the list that is specified by DestinationInstanceIds.

    Valid values:

    • false (default): The match is successful if the destination instance IDs are in the list that is specified by DestinationInstanceIds.

    • true: The match is successful if the destination instance IDs are not in the list that is specified by DestinationInstanceIds.

    Specify a community in the nn:nn format. Valid values of nn: 1 to 65535.

    You can specify up to 32 communities.

    A community must comply with the RFC 1997 standard. The RFC 8092 standard that defines BGP large communities is not supported.

    Note

    If the configurations of communities are invalid, routes may not be advertised to data centers.

    DestinationChildInstanceTypes

    List

    No

    Yes

    The destination instance types that are matched by using match statements.

    Valid values:

    • VPC

    • VBR

    Note

    This property is valid only when the routing policy is used for scenarios in which routes are advertised from regional gateways to destination instances in the same region.

    Priority

    Integer

    Yes

    Yes

    The priority of the routing policy.

    Valid values: 1 to 100. A smaller value indicates a higher priority.

    Note

    After you specify a priority for a routing policy, you cannot specify the same priority for another routing policy that is used in the same region and direction. The system evaluates routes against the match conditions of routing policies in descending order of priority. A smaller value indicates a higher priority. Therefore, you must specify appropriate values to sort the routing policies in the expected order.

    SourceChildInstanceTypes

    List

    No

    Yes

    The source instance types that are matched by using match statements.

    Valid values:

    • VPC

    • VBR

    AsPathMatchMode

    String

    No

    Yes

    The mode in which the autonomous system (AS) paths are matched by using match statements.

    Valid values:

    • Include: fuzzy match. The match is successful if the AS path of the route overlaps with the AS path that is specified in the match condition.

    • Complete: exact match. The match is successful only if the AS path of the route is the same as the AS path that is specified in the match condition.

    CidrMatchMode

    String

    No

    Yes

    The mode in which the prefixes are matched by using match statements.

    Valid values:

    • Include: fuzzy match. The match is successful if the route prefix that is specified in the match condition contains the prefix of the route. For example, you can set the route prefix in the match condition to 1.1.XX.XX/16 to match a route whose prefix is 1.1.1.0/24 by using a fuzzy match.

    • Complete: exact match. The match is successful only if the prefix of the route is the same as the route prefix that is specified in the match condition. For example, you can set the route prefix in the match condition to 1.1.XX.XX/16 to match only a route whose prefix is 1.1.XX.XX/16 by using an exact match.

    MapResult

    String

    Yes

    Yes

    The action that is performed on a route if the route matches all match conditions.

    Valid values:

    • Permit: allows the route.

    • Deny: rejects the route.

    RouteTypes

    List

    No

    Yes

    The route types that are matched by using match statements.

    Valid values:

    • System: system routes that are generated by the system

    • Custom: custom routes that are created by users

    • BGP: BGP routes that are advertised to BGP

    You can specify multiple route types.

    Preference

    Integer

    No

    Yes

    The new priority of the route that is modified by using an action statement.

    Valid values: 1 to 100.

    Default value: 50.

    A smaller value indicates a higher priority.

    CommunityOperateMode

    String

    No

    Yes

    The mode in which communities are managed by using action statements.

    Valid values:

    • Additive: adds communities.

    • Replace: replaces communities.

    CenId

    String

    Yes

    No

    The ID of the CEN instance.

    None.

    NextPriority

    Integer

    No

    Yes

    The priority of the next routing policy that you want to associate with the current routing policy.

    Valid values: 1 to 100.

    • If you leave this property empty, no routing policy is associated with the current routing policy.

    • If you set this property to 1, the next routing policy is associated with the current routing policy.

    • If you set this property to a value other than 1, the priority of the next routing policy must be higher than the priority of the current routing policy.

    Only when MapResult is set to Permit, the system continues to match the matched routes by using the next routing policy.

    PrependAsPath

    List

    No

    Yes

    The AS paths that are prepended by using action statements when regional gateways receive or advertise routes.

    The requirements on AS paths that are prepended vary based on the direction in which the routing policy is applied:

    • When AS paths are prepended in the RegionIn direction, you must specify the source instance IDs and the source region in the match condition. The source region must be the same as the region in which the routing policy is used.

    • When AS paths are prepended in the RegionOut direction, you must specify the destination instance IDs in the match condition.

    CommunityMatchMode

    String

    No

    Yes

    The mode in which communities are matched by using match statements.

    Valid values:

    • Include: fuzzy match. The match is successful if the community of the route overlaps with the community that is specified in the match condition.

    • Complete: exact match. The match is successful only if the community of the route is the same as the community that is specified in the match condition.

    MatchAsns

    List

    No

    Yes

    The AS paths that are matched by using match statements.

    An AS path is a required attribute. An AS path describes the AS number that is used to pass a BGP route when the BGP route is advertised.

    Only AS SEQUENCE is supported. AS SET, AS CONFED SEQUENCE, and AS CONFED SET are not supported. In other words, only the AS number list is supported. Sets and sub-lists are not supported.

    SourceRegionIds

    List

    No

    Yes

    The source region IDs that are matched by using match statements.

    You can specify up to 32 source region IDs.

    Return values

    Fn::GetAtt

    RouteMapId: the ID of the routing policy.
