| AggregationType | uint16 | |
| Description | string | Route aggregation refers to summarizing ranges of routes into one or more aggregate routes. This is done to minimize the number of routes in the global routing table. A potential drawback is that specific path information (e.g., the Path attribute value) is lost, which may lead to potential routing loops. There are a variety of ways to ensure that this does not happen. Note that BGP4 is required to do this.
There are many ways to form aggregate routes. The following are the most popular: 'Aggregate only', where only the aggregate is advertised, and all of its more specific routes are suppressed; 'Aggregate Plus Specific Routes', where both the aggregate as well as its more specific routes are advertised (e.g., send the aggregate to the NAP, but send the more specific routes to providers); 'Aggregate Based on a Subset of Specific Routes', where the aggregate route is formed by looking at certain more specific routes and forming an aggregate on them, suppressing all others. |

| ASNumber | uint16 | |
| Deprecated | string | CIM_AutonomousSystem.ExtASNumber |
| Description | string | Depricated for ExtASNumber which is a 4 octet numbers in the form x.y, where x and y are 16-bit numbers. Numbers of the form 0.y are exactly the old 16-bit AS numbers.
An ASNumber is an integer between 1 and 65535, with the range 64512 through 65535 reserved for private use. Every AS has a unique AS number, which is assigned to it by an Internet Registry or a provider. IANA assigns and administers AS numbers. |
| ExtASNumber | string | |
| Description | string | A 4 octet numbers in the form x.y, where x and y are 16-bit numbers. Numbers of the form 0.y are exactly the old 16-bit AS numbers.Every AS has a unique AS number, which is assigned to it by an Internet Registry or a provider. IANA assigns and administers AS numbers. |
| IsSingleHomed | boolean | |
| Description | string | IsSingleHomed is a boolean that, when its value is TRUE, indicates that this AS reaches networks outside of its domain through a single exit point. |
| IsTransit | boolean | |
| Description | string | IsTransit is a boolean that, when its value is TRUE, indicates that this AS will advertise routes that it learns from other ASs. A non-transit AS will only advertise its own routes. |
| RequireIGPSync | boolean | |
| Description | string | RequireIGPSync is a boolean that, when its value is TRUE, indicates that this AS must obey the following rule: a router should not advertise destinations learned from internal neighbors to external destinations unless those destinations are also known via some internal gateway protocol. Otherwise, a router may receive traffic that cannot yet be routed. However, since this is a costly choice, it is common practice to allow this rule to be broken under certain carefully controlled circumstances. |
| RoutingUpdateSource | uint16 | |
| Description | string | RoutingUpdateSource defines how routing information is to be injected. Statically injected routes are maintained by the routing table and are independent of the status of the networks to which they refer. This is done simply by defining static routes in the routing table. Dynamically injected routes are of two types. Dynamic routes refer to distributing all of the IGP routes. Semi-dynamic routes define a set of specific IGP routes that will be injected. |
