Configure Aggregate IPv6 Routes

Configure IPv6 aggregate routes so that the router advertises a single route (aggregate route) that represents all destinations. Aggregate routes also reduce the size of routing tables.

To configure aggregate routes for IPv4, see Configure Aggregate Routes.

Before you begin

Aggregate routes are enabled.
You have determined the appropriate aggregate prefix and length.
If required, policies exist.
To perform this procedure on a non-default VRF, you must first change the VRF instance. For information about how to use EDM for a non-default VRF, see Select and Launch a VRF Context View. All parameters might not be available in non-default VRFs.
The VRF must have an RP trigger of BGP.

Procedure

In the navigation pane, expand Configuration > IPv6.
Select BGP+.
Select the Aggregates tab.
Select Insert.
Specify the aggregate Address and PrefixLen
Optional: Configure AsSetGenerate and SummaryOnly as required.
Optional: Configure policies for the aggregate route.
Select Insert.

Aggregates field descriptions

Use the data in the following table to use the Aggregates tab.


Name	Description
Address	Specifies the aggregate address. The default is none.
PrefixLen	Specifies the length of the prefix (in bits).
AsSetGenerate	Enables or disables AS-set path information generation. The default is disable.
SummaryOnly	Enables or disables the summarization of routes in routing updates. Enable this parameter to create the aggregate route and suppress advertisements of more-specific routes to all neighbors. The default is disable.
SuppressPolicy	Specifies the route policy (by name) used for the suppressed route list. Enable this parameter to create the aggregate route and suppress advertisements of the specified routes.
AdvertisePolicy	Specifies the route policy (by name) used for route advertisements. The route policy selects the routes that create AS-set origin communities.
AttributePolicy	Specifies the route policy (by name) used to determine aggregate route attributes.
