r/gns3

Hey everyone,

I’m currently setting up a Cisco XRv 9000 image inside GNS3, but I've run into an annoying roadblock. Right now, I can only get the IOS CLI to load if the node's console type is set to VNC (Which is the normal behavior as far as I know).

I want to switch the console type over to Telnet so I can just use my normal terminal via PuTTy but whenever I blindly change the GNS3 node settings to Telnet, the XRv boots up into the kernel mode not the ios CLI, and can''t seem to overwrite this.

I've tried many Additional Settings within the QEMU Additional Options like -vga std.. but nothing..

I stumbled across this GNS3 guide for ASAv devices which handles a similar issue:https://www.gns3.com/how-to-configure-any-asav-qcow2-

However, the steps and QEMU settings there are specific to the ASA platform and don't seem to translate directly to the XRv9k architecture.

Does anyone know the proper workflow or specific QEMU/advanced settings needed to successfully force the XRv 9000 to pipe the cisco ios via Telnet instead of VNC?

Appreciate any help or pointers you can give!

I made a MPLS lab on gns3 where it has the topology as such. the router i used is iso Cisco c7200 , i connected the first cloud to host device through loopback interface, the other cloud connected to Ubuntu machine on VMware through VMnet2 virtual interface.

The ping test was successful between the two devices and there's no packet loss, but when i tried to make Iperf3 test with 10 samples of packet bursts (from 1 to 10 mbps) the output shows that there's a **99% packet loss** with 1.2 ms latency.

The routers configuration is correct and working as it should be so i don't think its a configuration related problem more than cloud interfaces problem.

has anyone came through problem like this and if anyone could help please?

Thanks in advance.
