Support for ECMP in host table
ECMP support in the L3 host table is available on the system. IPv6 /128 prefix route entries and IPv4 /32 prefix entries which are
moved to host table can have ECMP. For other platforms, only the IPv6 /128 prefix route entries is stored in the L3 host table
without ECMP support.
The software supports a command to program IPv6 /128 route prefixes in the host table.
The output of show IPv6 cam command has been enhanced to include the ECMP field in the Neighbor table of Ipv6 CAM. The
sample output is displayed as follows, which is similar to the prefix table.
The following is the portion of the example output:
