Re: [vpp-dev] Problem on VxLAN multicast mode

Hi, Xuekun, Packets are only received on unicast tunnels. So in your case you would need to create one and put it under the bridge-domain (the multicast tunnel does not need to be under the bridge-domain): create vxlan tunnel src 172.168.1.1 dst 172.168.1.2 vni 100 set interface l2 bridge

Re: [vpp-dev] Problem on VxLAN multicast mode

Just to clarify, the mcast tunnel does not need to be under the bridge for receiving traffic, however for sending flooded traffic through the mcast tunnel it needs to be under the bridge... eyal On 05/11/2018, 13:47, "vpp-dev@lists.fd.io on behalf of eyal bari via Lists.Fd.Io" wrote:

Re: [vpp-dev] Problem on VxLAN multicast mode

Hi, Eyal If need to create a unicast tunnel also, it means need to know the remote vtep address first. However the purpose of using mcast tunnel is to build tunnels across multiple vtep addresses which don't be known in advance. For example, if there is a third server (server3: 192.168.1.3) in

Re: [vpp-dev] Problem on VxLAN multicast mode

VPP does not support receiving of VXLAN packets from an unknown VTEP. Thus, any packet received in a BD from a VXLAN multicast tunnel must have its source IP match of the remote VTEP of an existing VXLAN unicast tunnel in the same BD. If no such unicast tunnel is found, packets are dropped. I

[vpp-dev] VPP handles deleting ACL's and MACIP's differently

VPP handles deleting ACL's and MACIP's differently. In the file /vpp/src/plugins/acl/acl.c The function `acl_del_list` checks to see if the ACL being deleted is being referenced by an interface and returns an error if it is. The function `macip_acl_del_list` will remove the MACIP and remove a

Re: [vpp-dev] Problem on VxLAN multicast mode

To answer another question from Xuekun about usage of VXLAN mcast tunnel, the advantage is that flooding to remote VTEPs only needs to send one packet into the mcast tunnel. If there is no mcast tunnel, VPP will need to send a packet per unicast VXLAN tunnel to flood all remote VTEPs.-John

Re: [vpp-dev] VPP handles deleting ACL's and MACIP's differently

Hi Stephen, Yeah I think the current behavior with the “acl_del_list” was what we arrived to after the discussion on the list, but the macip ACL behavior never got updated. One can harmonize the behavior, though to ensure no pain it would take some time - 1) add a startup config variable (off
