cam-ipv6 extended-prex
Enable LPM partitioning to support IPv6 /65 to /128 route prexes to be stored in Partition 1.
Syntax
cam-ipv6 extended-prefix <Max-IPv6-prefixes>
To remove LPM partitioning conguration, use no cam-ipv6 extended-prex.
Parameters
Max-IPv6-Prex Maximum number of IPv6 prexes 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 prexes are not converted to /64 prexes and are
installed and saved in LPM. All the packets for those routes traverse through the default route path.
