Configuring IPv6 Address Ranges with Next Hop Forwarding Address

To configure the IPv6 address with the next hop configuration for IPv6 pools and address ranges, use the following sample configuration:

configure 
   ipam
      instance instance_id 
         address-pool pool_name 
            ipv6 
            address-ranges 
               address-range start_ipv6_address end_ipv6_address nexthop-forwarding-address nexthop_forwarding_address 
               prefix-range prefix_value length prefix_length nexthop-forwarding-address nexthop_forwarding_address 
                 split-size per-cache number_of_addresses 
                 split-size per-dp number_of_addresses 
                 exit  
                 prefix-range prefix_value length prefix_length nexthop-forwarding-address nexthop_forwarding_address 
               commit 

NOTES:

  • address-pool pool_name : Specify the name of the address pool. pool_name must be a string.

  • ipv6 : Enter the IPv6 mode of the pool.

  • address-ranges : Specify the IPv6 address ranges and prefix range addresses with the next hop forwarding address.

    Note
    IANA IPv6 configuration is used by BNG.
    • address-range start_ipv6_address end_ipv6_address : Specify the starting and the ending addresses of the IPv6 address range.

    • nexthop-forwarding-address nexthop_forwarding_address : Specify the nexthop forwarding address.

    • prefix-range prefix_value length prefix_length : Specify the prefix value and length within the IPv6 address.

    • nexthop-forwarding-address nexthop_forwarding_address : Specify the next hop forwarding address.

  • prefix-ranges : Specify the prefix ranges of an IPv6 address.

    Note
    SMF supports only IAPD IPv6 configuration.
    • split-size per-cache number_of_addresses : Specify the number of IPv6 addresses per chunk for IPAM cache allocation.

    • split-size-per-dp number_of_addresses : Specify the number of IPv6 addresses per chunk for the Data plane allocation.

    • prefix-range prefix_value length prefix_length nexthop-forwarding-address nexthop_forwardng_address : Specify the prefix value and the length within the IPv6 address with the next hop forwarding address.

Configuration Example

The following is an example configuration.

ipam
 instance 1
  address-pool ISE-Pool1
   vrf-name ISP   
   tags
    dnn cisco_vlan400.com  
   exit
   ipv6
    address-ranges                            
      address-range 1000::1 1000::ffff nexthop-forwarding-address :9001::3
      prefix-range 2607:fc20:1010:: length 98 nexthop-forwarding-address :9001::3
    prefix-ranges 				
       split-size
       		per-cache 32768
       		per-dp    32768
       exit
       prefix-range 2607:fc20:1010:: length 44 nexthop-forwarding-address :9001::3
   exit
  exit
