Bundle Ethernet not coming up on IOSXRv

Hi All,

I am trying to build up a lab with couple of iosxrv ans nxos9000v. My first issue is that my bundle ethernet is not coming up between the xr platforms (I am using 2 interface), below is the config:

 

 

RP/0/0/CPU0:Router-A-1#show run int gigabitEthernet 0/0/0/0
Mon May 21 18:14:41.004 UTC
interface GigabitEthernet0/0/0/0
bundle id 10 mode active
cdp
lacp period short
!

RP/0/0/CPU0:Router-A-1#show run int gigabitEthernet 0/0/0/1
Mon May 21 18:14:42.464 UTC
interface GigabitEthernet0/0/0/1
bundle id 10 mode active
cdp
lacp period short
!

RP/0/0/CPU0:Router-A-1#show run int be10
Mon May 21 18:14:45.504 UTC
interface Bundle-Ether10
bundle maximum-active links 3
load-interval 30

Re: Bundle Ethernet not coming up on IOSXRv

Are you using xrv or xrv-9k? If former, I'm not sure we support LACP. Try with bundle mode on.

Re: Bundle Ethernet not coming up on IOSXRv

I am using xrv, I tried to form the bundle using mode on also but that too didn't work. Do you see any missing config I pasted earlier if I change the mode from active to on?

Beginner

Re: Bundle Ethernet not coming up on IOSXRv

Nothing is missing in the config. Use the "sh bundle platform-capability" to check whether xrv can do bundles. XRV doesn't have a data plane, so none of the L2 features is supported. XRV9k has both a control and data-plane component, so it does support L2 features (in latest releases).

Re: Bundle Ethernet not coming up on IOSXRv

apparently sh bundle platform-capability doesn't even run in xrv and because I have only 32gb ram, I am not able to run couple of iosxr9000v. Can you suggest any other way to work on xr9000v images?

Re: Bundle Ethernet not coming up on IOSXRv

I have tried with mode on as well but still its not up.

Re: Bundle Ethernet not coming up on IOSXRv

I had this problem as well on XRv due to this being a virtualized platform.

 

"show bundle bundle-ether 3"

if you see the links stuck in replicating is due to a platform limitation

 

i have not tried on xrv9k yet

Hi folks,

 

Also what is important to note once you move onto ASR9000v or any other platform capable of LACP,

–is that LACP will still not work by default because the links between the VMs will be made of linux bridges or OVS bridges –which do not forward L2 BPDUs (like LACPDUs) by default.

 

I use OVS for my p2p backbone links between VMs when simulating networks (A-end and B-end interfaces in the same VLAN on a common OVS –so one OVS for all p2p links between all VMs).

And the solution was to enable the following on the OVS bridge for p2p links:

sudo ovs-vsctl set bridge <bridge-mane> other-config:forward-bpdu=true

Re: Bundle Ethernet not coming up on IOSXRv

and where should I run this command

"sudo ovs-vsctl set bridge <bridge-mane> other-config:forward-bpdu=true"

 

I have no idea about linux and not sure if I can run this command in the cli of the switches.

Participant

Re: Bundle Ethernet not coming up on IOSXRv

Yes this would be run on a the hypervisor (on the linux system running the asr9k VMs) in case you’re using OVS to connect the two router VMs together like this:

ASR9000v-A-------OVS-------ASR9000v-B
