Bug Description

Physical servers connected directly to the MX can be made part of a contrail VNs by creating physical/logical interfaces on physical router objects. Once this is done, the physical server should have L2/L3 connectivity to all the other hosts (VMs/BMS) in that VN.

When this setup is first configured, it is seen that the control node will not advertise an inclusive multicast route into the EVPN towards the MX. As a result, ARP requests that are coming from the physical server connected to the MX are not flooded into the VN. Restarting the control node fixes this issue.

Topology:

physical_server(192.168.255.240)--MX--(192.168.255.230)Contrail_VM

ARP request from the physical server for contrail_VM is not flooded by MX into the contrail VN.

Can you check if the CN has a route for the broadcast mac from the
vrouter agent which has the VM in question? CN generates the IM
route based on the broadcast MAC route received from the agent.

When you get a chance, can you remove the R3.0 scope - it should be tracked
via Trunk since we haven't created a R3.0 branch yet.

Further debug with Nischal revealed:

Agent is sending the broadcast mac route to the CN, albeit with the label set to 0. CN has an explicit check to not generated an inclusive-multicast route if label == 0.

no longer affects: juniperopenstack/r3.0

Nischal Sheth (nsheth) wrote :

Restarting an agent causes the agent to advertise a fresh broadcast
mac route, which has the correct label. That results in the CN adding
the requisite IM route. This also explains why restarting the CN fixes
all the IM routes.

Agent didnt send proper label in evpn inclusive replication.

Problem:
While exporting subscription for inclusive replication tree when local peer was
only added, exporter used to search for multicast_peer. In its absence it will
mark label as 0. In case local_vm_peer(local interface list) gets added before
local-peer, it will result in creation of path with multicast_peer, hence label
will be picked as vxlan-id.

Solution:
Before picking label as 0 check for presence of local_peer as well and pick up
vxlan of same as label.

Correct the metadata string of fip-pool to vn

The metadata mentioned in xsd for the link between floating-ip-pool to
VN is "virtual-network-floating-ip-pool" and Agent is adding a rule
in dependency manager for VMI as "floating-ip-pool-virtual-network".
This is resulting in no InterestedEvent in dependency tracker if the
link added between VN-FIP is the last link in that VMI.

As a fix, metadata is corrected in Agent.
