Primary Requirement ID | Secondary Requirement ID | Unit Test ID | Unit Test Description |
|---|
|
|
| - MR Node with Multiple interfaces
- Add UDSP rule that gives one of the local interfaces highest priority
- Send a PING
- Verify that the NID with the highest priority was used
- Send a PING
- Simulate an <error>
- PING msg should be queued on resend queue
- PING msg will be resent on a different interface
- Failed interface's health value will be decremented
- Failed interface will be placed on the recovery queue
- Eventually health score should recover so then only the preferred interface will be used (sensitivity > 0)

|
| - MR Node with Multiple interfaces: configure two networks, two NIDs on each network
- Add UDSP rule that gives one of the networks highest priority
- Start traffic
- Stop traffic
- Verify that NIDs on the network with the highest priority were used
- Start traffic
- Simulate an <error> (drop on one of the NIDs on the highest priority network)
- Failed interface's health value will be decremented
- Failed interface will be placed on the recovery queue
- Verify that the remaining interface on the failed network is used
- Eventually health score should recover so then only both interface on the preferred network will be used (sensitivity > 0)

|
| - Configure single local network with two NIDs on the network
- 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 local network as preferred
- Start traffic
- Stop traffic
- Verify that the preferred router was used
- Add a PUT drop rule on the router to drop traffic on one of the interfaces.
- Verify that traffic goes to the other interfaces of the preferred router. There shouldn't be any drop in traffic.
- Add a PUT drop rule on the router to drop traffic on all interfaces.
- Verify that traffic goes through the non-preferred router until one of the interfaces of the preferred router recovers.
