Hi

Any one tried ether-channel / port-channel with IOS-XRv9k image 6.2.x on EVE-NG?

It seems this L2 feature is supported as it has got DATA plane support. I tested MPLS L2 VPN P2P, traffic is passing.
Noticed the below link/discussion and according to that, XRv9k, supports port-channel.

https://community.cisco.com/t5/xr-os-an ... -p/3390432

Any idea whether EVE-NG has any limitations or not supported yet?

I am using Community Edition Version 2.0.3-92 and did not try on 2.0.3-95. I am not sure whether it works on Ver 2.0.3-95.

Mathew

Works my dear:
just make a note this image is super heavy !!!
2 XRv9k require min 8 CPU and 32G RAM

XRv9K vers 6.6.2

And STOP blame EVE here...
if image does not support something it is not EVE Issue, EVE supports ALL what current images does... !!!!!!!!!
6.6.2 image does not support
bundle load-balancing hash src-ip
Rest is fine
Uldis

Hi,

First thanks for the reply and sorry that I suspected EVE-NG but I was asking and was not aware of the those XRv9k limitations.

However, I tried but I can not get the IP connectivity and tried to set the "bundle load-balancing hash dst-ip" but commit failed - see below.
Also I have shared the bundle interface status and configuration.

Can you please share your configuration that worked in your setup to get IP connectivity?

I am wondering what is missing here to get the IP connectivity between the PE1 and PE2 when bundle interfaces are UP on both side. My topology is same as yours - PE1 and PE2 on G0/0/0/2 and G0/0/0/3 with Bundle interface 12.

Hi

Thank you for the reply.

I did the same configuration but I still can not ping between the two routers. I reloaded the two routers, EVE-NG etc.

BTW, I use RAM 16384 and CPU 4 for each XRv9k.

Do you think this is the issue?
is it possible to help check you can get it to work with this RAM and CPU in your setup?

Accordingly, I will add more RAM, if the issue is RAM.

Mathew

My eve where I tested is:
Dual CPU X5680, 80Gb RAM
EVE VM on esxi 6.0.
EVE Pro 2.0.5-21

Hi,

Thank you very much for checking on this.

I found the issue from logs - it was duplicate MAC address under bundle-ether 12. Because "/opt/qemu/bin/qemu-img commit virtioa.qcow2" failed on the 2nd one and success on 1st one, I copied the virtioa.qcow2 from 1 to 2 folder. This might have caused the same MAC address.

I had to add "mac-address 1e.bd01.503X" under bundle interface to fix it.

L3 reachability is good between the 2 routers now.

BTW, is there any good/easy fix for "/opt/qemu/bin/qemu-img commit virtioa.qcow2" failes?
In my server, always, only first one worked.

Dear Mat,
my serious advice to you, want do labs on eve, go to EVE Pro
But its good that you figured it..

Uldis

Hi,

Thanks for the support and advice.

Do you mean to say that for the below fix is in EVE-NG Pro and not in Community edition any more?
