Command Description:

 

To create an aggregate entry in a BGP or multicast BGP database, use the aggregate-address command in address family or router configuration mode.


Example:

 

The following example shows how to create the aggregate route for 193.*.*.*, and also suppress advertisements of more specific routes to all neighbors:

 

  Router(config)#router bgp 5 
  Router(config-router)#aggregate-address 193.0.0.0 255.0.0.0 summary-only

 

In the following example, a multiprotocol BGP aggregate address is created in address family configuration mode and applied to the multicast database only using an IP Version 4 address family. More-specific routes are filtered from updates.


  Router(config)#router bgp 5
  Router(config-router)#address-family ipv4 multicast
  Router(config-router-af)#aggregate-address 193.0.0.0 255.0.0.0 summary-only
