I have an testlab with Openstack and mx80 (16.1).
Two vrf instances - one to organize overlay network, one for vxlan tenants, and one evpn instance for vxlan termination using pim sparse scheme.
Initially muticast tunnels doesn't work and irb unit for vxlan tenants is in down state.
Irb goes up only after strange kick. First vxlan tunnel must be destined for vtep-source-address, irb goes up and multicast VTEPs starts work.
Is any way to fix this behavior?
Thanks!
