This test verifies basic control plane resilience from an ONOS Instance failure using SegmentRouting via pingall

It consists of

1. Configure and Install ONOS
2. Start Mininet and check flow state
3. Pingall
4. Induce a ONOS failure
5. check flow state
6. Pingall

Requirements

• An updated version of the CPQD switch has to be running to make sure it supports group chaining.

The test is executed using the netcfg subsystem: 1) APPS=openflow-base,netcfghostprovider,lldpprovider

The test runs for different topologies:

• 2x2 Leaf-Spine and 3-node ONOS cluster
• 4x4 Leaf-Spine and 3-node ONOS cluster
• Single switch and 3-node ONOS cluster
