• Configure single local network with two NIDs on the network  (RemoteLayout1)
• Configure two routers/gateways each providing access to a remote network
• Configure remote peer to have access to the remote network with two NIDs
• Add UDSP rule that designates a pair of a router and remote peer NIDs as preferred
• Add UDSP rule that gives the same remote peer NID highest priority
• Start traffic
• Stop traffic
• Verify that the preferred remote peer NID and router NID were used

• Configure single local network with two NIDs on the network (RemoteLayout1)
• Configure two routers/gateways each providing access to a remote network
• Configure remote peer to have access to the remote network with two NIDs
• Assign higher route priority to the route using gateway 1

• Configure two local networks (net1, net2) with two NIDs on each network (RemoteLayout2)
• Configure remote peer to have access to the remote network with two NIDs
• On peerA add UDSP rule that designates gateway 1 as preferred for all NIDs on peerB
• Start traffic (peerA to peerB)
