Configuring a Named Address Range for Dynamic Address Assignment

You can optionally configure multiple named ranges, or subsets, of addresses within an address-assignment pool. During dynamic address assignment, a client can be assigned an address from a specific named range. To create a named range, you specify a name for the range and define the address range.

To create a named range within an IPv4 address-assignment pool:

  1. Specify the name of the address-assignment pool and the IPv4 family.
    [edit access]user@host# edit address-assignment pool isp_1 family inet
  2. Configure the name of the range and the lower and upper boundaries of the addresses in the range.
    [edit access address-assignment pool isp_1 family inet]user@host# set range southeast low 192.168.102.2 high 192.168.102.254

To create a named range within an IPv6 address-assignment pool:

  1. Specify the name of the address-assignment pool and the IPv6 family.
    [edit access]user@host# edit address-assignment pool isp_2 family inet6
  2. Configure the name of the range and define the range. You can define the range based on the lower and upper boundaries of the prefixes in the range, or based on the length of the prefixes in the range.
    [edit access address-assignment pool isp_2 family inet6]user@host# set range dsl-range low 2008:2010:2011:0100::/64 high 2008:2010:2011:ffff::/64user@host# set range fiber-east prefix-length 48
