Examice · Accepted Answer

The configuration shown has static routes with multiple next-hop addresses specified for the 192.168.2.0/30 prefix, which implies that multiple equal-cost next hops will be installed in the forwarding table for the given prefix. This is indicative of load balancing or redundancy. For the 172.20.112.0/24 prefix, there are two next-hop addresses specified, which means that two next-hop interfaces will appear in the routing table for that prefix. The preference of the default route is set to 5, which is different from the default preference of 20, indicating that the route preference is not the same for each static route.

While installation of ECMP routes in the forwrding table is allowed, EX switches will not permit the use of a policy to accomplish this. Therefore, we must assume just one route will get installed on the fwd table. This is not the case for the routing table, which may host several equal cost routes.
