Platform and Infrastructure

  • All QFX5000 platforms supports DF only at port level granularity (In other words, for all evpn instances hosted on an ESI, only one of the Multihomed QFX5000 nodes can be DF). Below config options are recommended Have df-granularity knob (with which QFX5k platforms seem to have been qualified). Here, few bytes from esi value itself, instead of vlan-id are used for MOD-based DF. PR1672383

  • On QFX10008 devices, statistics for multicast packets is not as expected as the packets has the Layer 2 header stripped during replication in the Packet Forwarding Engine because of which it is not forwarded to the next hop. PR1678723

  • All QFX10000 devices might use udp port 67 as the source port in the VXLAN udp header. PR1727072
