CML router images - subinterface issue

[paul driver]

Hello
It seems the issue with sub-interfaces still hasn't been rectified, just download the latest CML modelling labs (2.4.1) and I'm still experiencing failure within (CML or Even-NG) Even using a different vm driver or carrier ethernet as a workaround. is now failing  

Can anyone else confirm if they are experiencing the same?

what router are you trying it was not working,  so I can check in my Lab and let you know.

i do remember using the CSR sub interface and worked as expected.

Hello @balaji.bandi 
TBH its failing on any L3  vm

csr 1000v-16/17
iosv -15.3 /15.7
c8000v 17
nxosv 7k

apologies paul asking this again, just before i confirm testing

are you looking to make sub interface as the example below was not working you mean? or I am totally misunderstanding you here, please?

interface Ethernet0/0
no ip address
!
interface Ethernet0/0.10
encapsulation dot1Q 20
ip address 10.10.200.1 255.255.255.0
!

Hello
Yes when using a simple sub-interface say to ROAS or when to tag a particular subnet off a routed interface, it doesn't work,

Its been a known issue as far i can see for a while and I used to get around it by using carrier BDI  or simply changing the vm network driver but I thought cisco would have fixed it by now in the new CML labs but it seems they haven't, 

Example:
L3 switch

vlan 10
int vlan 10
ip address 1.1.1.1 255.255.255.252

int x.x
description link to CSR
switchport host
switchport access vlan 10


CSR
int x/x
no shut
int x/x.10
description link to L3 sw
encapsulation dotq 10
ip address 1.1.1.2 255.255.255.252

The above will simply not work, however it will work if i make the sub interface native which suggests it related to tagging a routed interface.

i made a simple Lab in  (PNET - same as Eve-NG)  - I have CML 2.4 ( turned off) since I need Multi-Vendor to do some PoC testing, so PNETLab have good access for me.

Hello @balaji.bandi 
Cheers for testing i am aware that does work from my gns3 era

The earliest  IOS I have is ADVENTERPRISEK9-M), Version 15.9(3)M4 but I mainly IOS-XE which I download from cisco modelling labs and have installed on both CML and EVE but unfortunately i obtain the same failure on every vm (IOS and XE) up to the 8000v

[balaji.bandi]

just added v8000 device to my lab, i have tried v8000 still works for me

my v8000 Version 17.4.1prd14

Hello
Interesting, mine doesn't work, can you do one more test please Balaji
Can you put a L2 switch directly inbetween the two rtrs as subinterface level and test connection again

[balaji.bandi]

just change the topology :

[paul driver]

Hello
I am still getting failure, on both cml and eve ng, weird anyway thanks for the testing

try vmxnet3 (e1000 having issue)
