Example: Deleting a Mobility Address Pool

Requirements

• An operational MX Series chassis
• Junos OS MobileNext Broadband Gateway package

Example of Deleting a Mobility Address Pool

In this example, a pool “juniper-pool” in routing-instance “default” exists with the following configuration:

juniper-pool {
    family inet {
        network {
            30.30.0.0/16 {
                range {
                    range1 {
                        low 30.30.1.1;
                        high 30.30.255.254;
                    }
                }
            }
        }
    }
    default-pool;
}

In this example, you delete this pool.

Configuration

Step-by-Step Procedure

1. Enter configuration mode and place the pool in maintenance mode.
   user@host# configureuser@host# set access address-assignment mobile-pools juniper-pool service-mode maintenance user@host# commit
2. Wait for all sessions using “juniper-pool” to terminate. Do this by monitoring the service-mode status using the show command. When sessions become zero, the service-mode status will display Maintenance – Active Phase.
   user@host# run show unified-edge ggsn-pgw address-assignment service-mode pool juniper-pool

   Note: When maintenance mode shows “Maintenance – Active Phase,” the system is ready to accept configuration changes for all attributes of this object and its subhierarchies. When maintenance mode shows “In/Out Phase,” the system is ready to accept configuration changes only for non-maintenance mode attributes of this object and its subhierarchies.

3. Remove all references to the pool from all APNs, if any.
   user@host# delete unified-edge gateways ggsn-pgw MBG1 apn-services apn internet address-assignment inet-pool pool juniper-pooluser@host# commit
4. Remove all references to the pool from any pool group, if any.
   user@host# delete access address-assignment mobile-pool-groups pool-group-xyz juniper-pooluser@host# commit
5. If the pool is marked default pool, many APNs could be referencing this pool. In this case, delete the default pool attribute for the “juniper-pool.”
   user@host# delete access address-assignment mobile-pools juniper-pool default-pool user@host# commit
6. Delete the pool “juniper-pool.”
   user@host# delete access address-assignment mobile-pools juniper-pool routing-instance juniper-vrf user@host# commit
7. Verify that the address pool is deleted.
   user@host# run show unified-edge ggsn-pgw address-assignment pool details

   The address pool “juniper-pool” should not be displayed in the show command output.
