MXes in Junosphere
MXes in Junosphere are unsupported, but I tend to use them because I want something a bit closer to the real thing somehow. The VJX is ok, but I like the way the MX doesn’t come with any security-related stuff, and the interfaces start at ge-0/0/0 rather than ge-0/0/1!
The only downside with the virtual MX is that it is a non-supported image, unlike the VJX.
Sometimes when usign an VMX, you find that the topology starts up but you can’t SSH to one or two of the nodes. So you console onto it and discover that (for some reason) the management IP address has been put onto em0 rather than being where it should be in the member0 group applied to fxp0:
root@S1> show configuration groups member0 system { host-name S1; backup-router 10.233.255.254; } interfaces { fxp0 { unit 0 { family inet; <=== IP address missing! } } } root@S1> show configuration interfaces em0 unit 0 { family inet { address 10.233.248.46/20; <== Here it is. } }
The solution to this is to console onto the device and move Continue reading
