Hi all, I was learning about BGP-EVPN, and would need some help with bridge domains. Q1: Can you confirm I can re-use VLAN IDs in different bridge domains on a switch for different tenants? I mean a setup like this: Tenant A A B B L2 VNI 30100 30200 35100 35200 Bridge domain 1 1 2 2 Leaf switchport Eth1/8 Eth1/9 Eth1/15 Eth1/16 Mapped VLAN on leaf switchport to the VNI above 100 200 100 200 This way the dot1Q header would be the same on Eth1/8 and Eth1/15, yet they still would belong to a different L2 domain (VNI) because of the different bridge domain associated to them. Am I right or missing something here? Q2: If the answer to the above is yes, why are bridge domains available only on the N7k series and not on N9k & N5k? I mean this is an efficient way to offer all VLAN IDs to all tenants, and it doesn't even gets messy like it would with scoped leaf configuration. Thanks in advance. ... View more

Hi, Would it be possible to export releases of the VM in qcow2 too? The reason I'm asking is because GNS3 integration would be much simpler then: I can create a template (aka appliance) file for QEMU VMs and, using that, users can import the VM with a few clicks. (Here's an example.) I know that converting a vmdk to qcow2 is quite easy but we're checking the md5sum of the image file during import, and I'm not sure if users would get the same hash for their local conversions. ...

After a new install on KVM, the " Initializing database. Please wait until initialization process finishes." message stays on the web interface, even if I wait for a long time (30 minutes). I didn't see any error messages during the installation (install_log.txt) or at booting (1stboot_log.txt). I could assign an IP address, ping the VM and, as mentioned, access the web interface. This is the command I use to start the VM: /usr/bin/qemu-system-x86_64 -name vNAM 6.2.1b-1 -m 4096M -smp cpus=2 -enable-kvm -boot order=c -cdrom /opt/gns3/images/QEMU/nam-app-x86_64.6-2-1-b.iso -drive file=/opt/gns3/projects/0b46108e-6a81-4d27-b433-10b7801384ac/project-files/qemu/b6b784ae-5d35-41de-bdd8-dd12f3784612/hda_disk.qcow2,if=ide,index=0,media=disk -serial telnet:0.0.0.0:2001,server,nowait -monitor tcp:127.0.0.1:40905,server,nowait -net none -device virtio-net-pci,mac=00:00:ab:46:12:00,netdev=gns3-0 -netdev socket,id=gns3-0,udp=172.26.1.4:10000,localaddr=0.0.0.0:10000 -device virtio-net-pci,mac=00:00:ab:46:12:01 -machine type=pc-1.0,accel=kvm -nographic -rtc base=utc Show tech output is also attached.

I've made a small tool call vRIN (virtual Route Injector). It's a VM appliance that can be used to flood your topology with thousands of routes (tested in GNS3 with 1M BGP prefixes).  You can use it to bring the real world closer to your lab: test convergence times, learn summarization, check how ABRs work, etc.   Configuration is quite simple: connect the VM's NIC to your environment, boot it up either using windowed or headless mode (it can be reached through the serial console), set the parameters using the text-based menu, and generate the routes.   I tried to make it as small as possible; it only takes 256 MB memory, the virtual disk is ~500 MB.   Available in OVA an qcow2 (Qemu) formats. Download link: https://sourceforge.net/projects/vrin/files/   Questions, comments? Raise them here, or contact me on Twitter. Note: the same announcement was made on Learning Network but I think Support Community reaches more people. :) ... View more
