Busyout IP Pools

Busyout makes addresses from an IP pool in the current context unavailable once they are free.

Bulk Busyout IP Pools

Bulk Busyout IP pools is used to busyout:

All IP pools in a context
Specific Address range
Specific IPv4/IPv6 Pool – range of addresses in the pool or group of addresses in the particular IP pool, or range of IP addresses or group of IP addresses pools.

Bulk Busyout IP Pools by VRF Names

In P-GW, by configuring busyout ip pool using VRF name option you can busyout all the ip pools that are associated with the VRF.

For example, if there are 'n' number of ip pools that are associated with a vrf say vrf_1, then the configuration busyout ip pool vrf vrf_1 sets all the 'n' numbers of ip pools in busyout state. This busyout ip pool vrf configuration allows to avoid each pool to be marked busyout independently.

Enable Busyout IPv4 Pool with VRF

You can enable Busyout configuration for multiple IPv4 pools by using the CLI procedure.

Procedure

Step 1

Configure busyout for IPv4 pools based on VRF. The vrf_name is case-sensitive and you must enter the value of size 1–63.

busyout ip pool vrf vrf_name

Example:


[local]qvpc-si# config
[local]qvpc-si(config)# context context_name
[egress]qvpc-si(config-ctx)# busyout ip pool vrf vrf_name
[egress]qvpc-si(config-ctx)# end

Step 2

Verify whether the Busyout IPv4 pool is configured when the busyout configuration is in place for IPv4 pools.

Enable Busyout IPv6 Pool with VRF

You can enable Busyout configuration for IPv6 pools by using the CLI procedure.

Procedure

Step 1

Enable the busyout multiple IPv6 pools based on VRF. The vrf_name is case-sensitive and you must enter the value of size 1–63.

busyout ipv6 pool vrf vrf_name

Example:


[local]qvpc-si# config
[local]qvpc-si(config)# context context_name
[egress]qvpc-si(config-ctx)# busyout ipv6 pool vrf vrf_name
[egress]qvpc-si(config-ctx)# end

Step 2

Verify whether the busyout IPv6 pool is configured when busyout configuration is in place for IPv6 IP pools.

Disable Bulk Busyout by VRF for IPv4 Pools

You can disable bulk busyout by VRF configuration using the CLI procedure.

Note

Before unbusying a VRF, if an IP pool is already marked as busyout and associated with a VRF, and then when you configure or unconfigure VRF, the IP pool busyout status remains the same.

Procedure

Enter no to disable busyout for IPv4 pools based on VRF. If a pool associated with this VRF is marked as busyout then the IP pool stays busied out.

no busyout ip pool vrf vrf_name

Example:


[local]qvpc-si# config
[local]qvpc-si(config)# context egress
[egress]qvpc-si(config-ctx)# no busyout ip pool vrf vrf_name
[egress]qvpc-si(config-ctx)# end

Note

The vrf_name is case-sensitive and you must enter the values of size 1–63.

You have successfully disabled the busyout configuration for IPv4 pools.

Disable Bulk Busyout by VRF for IPv6 Pools

You can disable Busyout configuration for multiple IPv6 pools by using the CLI procedure.

Note

Before unbusying a VRF, if an IP pool is already marked as busyout and associated with a VRF, and then when you configure or unconfigure VRF, the IP pool busyout status remains the same.

Procedure

Enter no to disable busyout for IPv6 pools based on VRF. If a pool associated with this VRF is marked as busyout then the IP pool stays busied out.

no busyout ipv6 pool vrf vrf_name

Example:


[local]qvpc-si# config
[local]qvpc-si(config)# context egress
[egress]qvpc-si(config-ctx)# no busyout ipv6 pool vrf vrf_name
[egress]qvpc-si(config-ctx)# end

Note

The vrf_name is case-sensitive and you must enter the values of size 1–63.

You have successfully disabled the busyout configuration for IPv6 pools.
