When the same route (for example 2001:558:fe2a:218::/64) gets learned by two quagga instances and programmed to ONOS via FPM, only one of them gets installed. Instead, it should install both as ECMP.
onos> routes | grep 2001:558:fe2a:218::/64
> 2001:558:fe2a:218::/64 fe80::2a99:3aff:fe40:9f4b FPM (96.112.165.36)
2001:558:fe2a:218::/64 fe80::2a99:3aff:fe41:19db FPM (96.112.165.35)
The next-hop fe80::2a99:3aff:fe40:9f4b resides at of:0000000059120112/51, and the next-hop fe80::2a99:3aff:fe41:19db is at of:0000000059120111/51

In other words, the switch of:0000000059120111, even though it has a local reachability to
2001:558:fe2a:218::/64, sends traffic across the fabric to reach the prefix.
