Prefix Allocation (CPA/DPA) Tests

All Tests​

PUMA_IF_CPA1 Enable Centralized Prefix Allocation​

Description: This test is check if a network comes up with enabling centralized prefix allocation.

Test Setup: IF Fig-of-8 or largest IF setup available

Procedure:

  • Set the controller config enable_centralized_prefix as true, and prefixAllocParam using API service
  • Restart the e2e_controller.service
  • Recheck network state

Pass/Fail Criteria:

  • Network should come up with CPA enabled and the nodes in the network must have the prefixes provided by the controller.
  • Check the prefixes in the topology file on E2E to make sure, each node in the network has the prefix allocated by the controller.

PUMA_IF_CPA2 Disable Centralized Prefix Allocation and Re-Enable​

Description: This test is check if a network comes up with enabling centralized prefix allocation.

Test Setup: IF Fig-of-8 or largest IF setup available

Procedure:

  1. Bring up the network as specified in test CPA1.
  2. Recheck network state.
  3. Set the controller config enable_centralized_prefix as false using API service
  4. Give a delay of around 5 minutes
  5. Restart the e2e_controller.service
  6. Recheck network state
  7. Set the controller config enable_centralized_prefix as true using API service
  8. Give a delay of around 5 minutes
  9. Restart the e2e_controller.service
  10. Recheck network state

Pass/Fail Criteria:

  • Network should come up with CPA disabled after step 6.
  • Network should come up with CPA enabled after step 10 and the nodes in the network must have the prefixes provided by the controller.

PUMA_IF_DPA1 Enable Deterministic Prefix Allocation​

Description: This test is check if a network comes up with enabling deterministic prefix allocation.

Test Setup: IF Fig-of-8 or largest IF setup available

Procedure:

  • Set the controller config enable_deterministic_prefix as true
  • Restart the e2e_controller.service
  • Recheck network state

Pass/Fail Criteria:

  • Network should come up with DPA enabled

PUMA_IF_DPA2 Disable Deterministic Prefix Allocation​

Description: This test is check if a network stays up after disabling deterministic prefix allocation.

Test Setup: IF Fig-of-8 or largest IF setup available

Procedure:

  • Ignite the network with DPA enabled (enable_deterministic_prefix as true)
  • Set the controller config enable_deterministic_prefix as false
  • Restart the e2e_controller.service
  • Recheck network state

Pass/Fail Criteria:

  • Network should come up with DPA disabled
