VXLAN - GNS3 (VEOS \ IOU_L3)  Images:  Spine - IOU - i86bi_linux-adventerprisek9-ms.152-4.M1" Leaf -  vEOS - 4.13.16M-3213248.41316M.1   This was my first crack at configuring VXLAN i used a combination of vEOS and IOS because that is closest to what I run in my production environment. The actual vxlan configuration is very easy its more about making sure the underlying connectivity is in place. You can build the same lab in GNS3 using the CSR router and EIGRP which should be simpler (I had some issues with route summarization). The most important thing to confirm before starting on the vxlan configuration is that you have full reachability between all the loopbacks. Anyway it worked for me next step is doing this with EVPN. ################# ## SPINE-1 ## ################# conf t ## GENERAL ## hostname SPINE-1 ip multicast-routing ## INTERFACES ## int e0/1 ip addr 10.0.11.1 255.255.255.252 int e0/2 ip add...

Upgrading JUNOS via USB

I borrowed this guide from Juniper but keeping it here incase i cannot find it going forward. You need to have a fat32 or smaller than 4gb partitioned USB flash disk.  Enter the shell as root: user@switch> start shell user root Password: root@switch% Before inserting the USB device, perform the following: root@% ls /dev/da* /dev/da0 /dev/da0s1c /dev/da0s2a /dev/da0s3 /dev/da0s3e /dev/da0s1 /dev/da0s1f /dev/da0s2c /dev/da0s3c /dev/da0s1a /dev/da0s2 /dev/da0s2f /dev/da0s3d Insert the USB drive in the USB port. The following output will be displayed: root@% umass1: TOSHIBA TransMemory, rev 2.00/1.00, addr 3 da2 at umass-sim1 bus 1 target 0 lun 0 da2: <TOSHIBA TransMemory 5.00> Removable Direct Access SCSI-0 device da2: 40.000MB/s transfers da2: 983MB (2013184 512 byte sectors: 64H 32S/T 983C) root@% ls /dev/da* /dev/da0 /dev/da0s1c /dev/da0s2a /dev/da0s3 /dev/da0s3e /dev/da0s1 /dev/da0s1f /dev/da0s2c /dev/da0s3c /dev/da2 /dev/da0s1a /dev/da...
