Configuring 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.

Procedure

  1. In the navigation pane, expand Configuration > IPv6.
  2. Click BGP+.
  3. Click the Aggregates tab.
  4. Click Insert.
  5. Specify the aggregate Address and PrefixLen
  6. Configure AsSetGenerate and SummaryOnly as required.
  7. Configure policies for the aggregate route.
  8. Click Insert.
