Monitoring Address Pools Used for Subscribers
Purpose
Verify the pool used for NDRA, the delegated address pool used for DHCPv6 prefix delegation, and the length of the IPv6 prefixes that were delegated to the CPE.
Action
From operational mode, enter the show subscribers extensive command.

Meaning
Under the PPPoE session, the IPv6 Delegated Address Pool fields show the names of the pools used for DHCPv6 prefix delegation and for NDRA prefixes. The IPv6 Delegated Network Prefix Length field shows the length of the prefix used to assign the IPv6 address for this subscriber session. The IPv6 Interface Address field shows the IPv6 address assigned to the CPE interface from the NDRA pool.
Under the DHCP session, the IPv6 Delegated Address Pool fields show the name of the pool used for DHCPv6 prefix delegation. The IPv6 Delegated Network Prefix Length fields shows the length of the prefix used in DHCPv6 prefix delegation.
