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.

 

Hi,

The only commands tha I can type in address family under neighbor is:

activate                    Enable the Address Family for this Neighbor
  add-path                    Send or Receive multiple paths
  allowas-in                  Allow local AS number in as-path
  default-originate           Originate default route to this neighbor
  distribute-list             Filter networks in routing updates
  end                         Exit to the exec Mode
  exit                        Exit from current mode
  maximum-prefix              Maximum number of prefixes accepted from this peer
  next-hop-self               Disable the next hop calculation for this neighbor
  no                          Unconfigure BGP routing protocol
  route-map                   Name of the route map (max 140 chars)
  sender-side-loop-detection  Sender side loop detect for neighbor
  show                        show configuration

Any idea?
