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.
NoteIANA 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.
NoteSMF 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.
