Next-hop routing
The Linux networking stack supports ECMP by adding multiple next-hops to a route, and the kernel provides limited support for IPv6
multipath routing.

L3 routing topology
Use ip addr add or ifconfig to congure an interface.
See Application examples in the OpenSwitch OPX Developers Guide for more information on how to congure routing using the CPS API.
