Reference Guide

Use the ipv4 unicast-host-route or ipv6 unicast-host-route commands to program IPv4 /32 or IPv6 /128 route
prefixes to be stored in the L3 host table. A warning message states that the change takes effect only when IPv4 or IPv6 route
prefixes are cleared from the routing table (RTM) using the clear ip route * command. The IPv6 /128 and IPv4 /32
route-prefix entries that you move to the host table receive ECMP handling.
To verify ECMP support for IPv6 /128 route prefixes stored in the host table, use the show ipv6 cam command. The
command output includes the ECMP field with IPv6 neighbor addresses. 1 indicates ECMP handling of destination routes.

To re-enable programming of IPv6 /128 route prefixes in the LPM table, use the no ipv6 unicast-host-route command.
