The new BGP test suite requires some cluster configuration to be set.

The scheme is in attachment.

The suite should only be run on tlv2 clusters with ENVs (since it was only there that we managed to test and run the tests):

PRIMARY_NODE_NETWORK_VLAN_TAG=153
EXTERNAL_FRR_STATIC_IPV4=10.46.248.177/21 (reserved IP)

Important: a static IP means lack of parallelization (we can't have two parallel runs of the suite on different clusters)

Future possible enhancement: getting PRIMARY_NODE_NETWORK_VLAN_TAG via lldp and DHCP instead of static address (both are not working now). Once we achieve this, and then reflect the vlan requirements for each cluster type, the BGP test suite will become independent of the cluster type.
