Hello, I know this is a Cisco list, but maybe somebody will kindly help me with Brocade here. I have the following setup:
L2 switch --- ICX 7750 --- SOME IP NETWORK --- ICX 7750 --- L2 switch The VXLAN setup is really simple: vlan 100 name TEMP by port tagged ethe 1/1/33 interface ethernet 1/1/33 port-name TEMP vxlan vlan 100 vni 100 l2-tunnel 1 interface l2-tunnel 1 l2-tunnel mode vxlan eline l2-tunnel source 1.1.1.1 l2-tunnel destination 2.2.2.2 Connected to both L2 switches (on each side) there are PCs. Obviously on the same subnet (since VXLAN is L2 VPN). No PC on either switch is able to ping a PC on the opposite side – all of them isn’t able to resolve ARP! But the moment I put a static ARP entry in both PCs, they manage ping and communicate with each other. Therefore, VXLAN seems to be up, besides not forwarding ARP requests. The only difference I see, is ARP requests being sent to broadcast MAC address. Moreover, each PC is able to ping successfully the appropriate IP addresses on the switch close to it. So it doesn’t seem to be some L2 configuration/problem with the LAN on each side. Moreover, interestingly enough, all MAC addresses present in all switches across the LAN (yes, that includes MAC addresses from across the VXLAN). The setup is as simple as outlined above, and the ping responses stop if I disconnect the 7750 from the IP network between them (proof of the fact the LANs on each side are indeed communicating with each other across the VXLAN). Any ideas will be welcomed. Is there anything I need to add to the configuration for forwarding broadcast requests? Thank you. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
