Configuring APN to Enable Prefix Delegation From Local Pool

Configuration Overview

To enable prefix delegation from a local pool, perform the following steps:

Step 1

Configure the private pool name in the APN configuration mode, to be used for delegate prefix allocation.

Step 2

Configure the APN to enable or disable IPv6 prefix delegation or default prefix delegation from the local pool.

Configuring APN for Private Pool Name

Use the following steps to configure the APN profile on the GGSN/P-GW/SAEGW for enabling Prefix
Delegation from the local pool:

config

context context_name

apn apn_name

ipv6 address delegate-prefix-pool pool_name
no ipv6 address delegate-prefix-pool
end

config

context context_name

apn apn_name

ipv6 address alloc-method [dhcpv6-proxy | local | no-dynamic ] allow-prefix-delegation

pd-alloc-method local

ipv6 address delegate-prefix-pool pool_name
ipv6 address prefix-delegation-len [48 | 52 | 56]
end

Notes:

• delegate-prefix-pool: Configures a pool of IPv6 address delegated prefix.

pool_name: Name of the pool with IPv6 address delegated prefix.

• no: Disables the pool of IPv6 address delegated prefix.

• dhcpv6-proxy: Configures the IPv6 address from the DHCP server for the APN.

• local: Configures the IPv6 address from the local pool configured.

• allow-prefix-delegation: Configures the APN to allow DHCPv6 prefix-delegation.

• ipv6 address prefix-delegation-len: Configures the length of prefix (48/52/56) to allow with DHCPv6

prefix delegation.

Configuring Prefix Delegation on Destination Context

Use the following configuration to configure the APN profile on the GGSN/P-GW/SAEGW for enabling
Prefix Delegation from the Local Pool:

config

context context_name
