Configuring the LPM Table for IPv6 Extended
Prefixes
The LPM CAM table consists of two partitions: Partition I for IPv6 /65-/128 route-prefix entries and Partition II for IPv6 0/0-/64 and IPv4
0/0-0/32 route-prefix entries. You must reconfigure LPM CAM to allow IPv6 /65-/128 route prefixes to be stored in Partition I.
• Use the cam-ipv6 extended-prefix command to enable IPv6 /65-/128 route prefixes to be stored in LPM CAM Partition 1.
You must specify the maximum number of IPv6 prefixes with /65-/128 mask length that are supported in the partition. The valid
values are 1024, 2048 or 3072 prefixes. You must save the configuration and reload the switch for the change to take effect.
• The number of entries in Partition II is reduced as the number of entries in Partition I increases.
• To disable LPM CAM partitioning and return the number of the IPv6 /65-/128 route prefixes stored in Partition 1 to 0, enter the no
cam-ipv6 extended-prefix command.
• Use the show cam-ipv6 extended-prefix command to display the currently configured number of IPv6 /65-/128 prefixes
that can be stored in LPM CAM Partition 1 and the number that are supported after the next switch reboot.
ICMPv6
ICMP for IPv6 (ICMPv6) combines the roles of ICMP, IGMP and ARP in IPv4. Like IPv4, it provides functions for reporting delivery and
forwarding errors, and provides a simple echo service for troubleshooting. The implementation of ICMPv6 is based on RFC 4443.
ICMPv6 uses two message types:
• Error reporting messages indicate when the forwarding or delivery of the packet failed at the destination or intermediate node. These
messages include Destination Unreachable, Packet Too Big, Time Exceeded and Parameter Problem messages.
• Informational messages provide diagnostic functions and additional host functions, such as Neighbor Discovery and Multicast Listener
Discovery. These messages also include Echo Request and Echo Reply messages.
The ping and traceroute commands extend to support IPv6 addresses. These commands use ICMPv6 Type-2 messages.
