Configure Aggregate Address on Tenant VRF

You can configure “aggregate-address” (to be advertised by BGP) per tenant VRF (and device) when you create or update a VRF. EFA provisions the “aggregate-address” on switches when VRF is instantiated or updated on the switches.

Procedure

  1. To configure “aggregate-address” when you create a tenant VRF, run the following commands:
    When you trigger L3 EPG create or L2 EPG transition to L3 EPG, VRF is instantiated on the switches based on the endpoints present in the EPG.
    efa tenant vrf create --name <vrf-name> --tenant <tenant-name> 

                 --ipv4-aggregate-address <device-ip,aggregate-address> 
                 --ipv4-aggregate-summary-only <device-ip,aggregate-address,true|false>
                 --ipv4-aggregate-as-set <device-ip,aggregate-address,true|false> 
                 --ipv4-aggregate-advertise-map <device-ip,aggregate-address,route-map>
                 --ipv4-aggregate-suppress-map <device-ip,aggregate-address,route-map>
  2. To configure “aggregate-address” when you update a tenant VRF, run the following commands:
    When you trigger VRF update operation, VRF is updated on the switches based on the endpoints present in the EPGs using the VRF.
    efa tenant vrf update --name <vrf-name> --tenant <tenant-name> 

                 --operation aggregate-address-add| aggregate-address-delete

                 --ipv4-aggregate-address <device-ip,aggregate-address> 
                 --ipv4-aggregate-summary-only <device-ip,aggregate-address,true|false>
                 --ipv4-aggregate-as-set <device-ip,aggregate-address,true|false> 
                 --ipv4-aggregate-advertise-map <device-ip,aggregate-address,route-map>
                 --ipv4-aggregate-suppress-map <device-ip,aggregate-address,route-map>

  3. Verify the switch configuration on the SLX device.
