cam-ipv6 extended-prefix

Enable LPM partitioning to support IPv6 /65 to /128 route prefixes to be stored in Partition 1.

Syntax
cam-ipv6 extended-prefix <Max-IPv6-prefixes>

To remove LPM partitioning configuration, use no cam-ipv6 extended-prefix.

Parameters
Max-IPv6-Prefix
Maximum number of IPv6 prefixes in the mask length of /65 to /128. The possible values are 1024, 2048, and 3072.
Defaults
LPM is not partitioned with Partition 1 and therefore /65 to /128 prefixes are not converted to /64 prefixes and are installed and saved in LPM. All the packets for those routes traverse through the default route path.
