Address familly BGP prefix aggregation

Hello,

To assign aggregation only for a specific neighbor in BGP on Dell Networking OS10, you can use the following steps:

Log in to the OS10 switch using a SSH or console session.

Enter the global configuration mode by typing configure and pressing Enter.

Access the BGP configuration by typing router bgp and entering the BGP autonomous system (AS) number.

Specify the neighbor for which you want to assign the aggregation by typing neighbor <neighbor-IP> and entering the IP address of the specific neighbor.

Enter the address-family configuration mode for IPv4 unicast by typing address-family ipv4 unicast.

Enable the aggregation for the specific neighbor by typing aggregate-only command.

Configure the specific aggregation parameters for the neighbor, such as the network prefix and mask, by using the aggregate-address command followed by the desired parameters.

Here's an example of how the configuration might look:

configure

router bgp <AS-number>

neighbor <neighbor-IP>

   address-family ipv4 unicast

     aggregate-only

     aggregate-address <network-prefix> <mask>

   exit-address-family

exit

exit

Replace <AS-number> with the BGP autonomous system number, <neighbor-IP> with the IP address of the specific neighbor, <network-prefix> with the network prefix you want to aggregate, and <mask> with the corresponding subnet mask.

Save the configuration by typing copy running-configuration startup-configuration to ensure that the changes are persistent across reboots.
