Hi all,
I am trying to learn VPLS for the first time, so I did a lab with EVE-NG and CSR-1000v as PEs. As CEs I have old 7206 Dynamips routers.
I am following the MPLS Fundamentals Book but some parts of it, especially the chapter about VPLS seems quite dated, since it presents commands that doesn't even exist anymore with the same syntax (such as xconnect vfi) on newer platforms.
Then I came across this guide: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_l2_vpns/configuration/xe-3s/mp-l2-vpns-xe-3s-book/mp-vpls.html#task_ECF53F9207A94801B40382B32031ACAE
Which presents more current info with newer commands and syntaxes. All commands are available on the CSR-1000v but I am absolutely missing something, so I have a few questions.
1. Does VPLS on EVE-NG CSR1000v even work? Has anybody tried it sucessfully?
2. I am using the configuration below, which seems correct, but I cannot see an AC (attachment circuit) on the VFI. So I think either I missing something important or VPLS doesn't work on EVE for some reason.
Here's my config:
PE26 (CSR1000v):
l2vpn vfi context teste
vpn id 1
l2protocol forward cdp
member 150.1.28.28 encapsulation mpls ! That is PE27
! Interface to the local CE
interface GigabitEthernet2
description TO-SW19 ## CLIENTE D
no ip address
negotiation auto
no mop enabled
no mop sysid
service instance 1 ethernet
encapsulation dot1q 1-4094
!
bridge-domain 1
member GigabitEthernet2 service-instance 1
member vfi teste
PE27 (CSR-1000v):
l2vpn vfi context teste
vpn id 1
l2protocol forward cdp
member 150.1.26.26 encapsulation mpls ! That is PE26
! Interface to the local CE
interface GigabitEthernet2
description TO-SW20 ## CLIENTE D
no ip address
negotiation auto
no mop enabled
no mop sysid
service instance 1 ethernet
encapsulation dot1q 1-4094
!
bridge-domain 1
member GigabitEthernet2 service-instance 1
member vfi teste
Verification results:
PE26#show vfi
Legend: RT=Route-target, S=Split-horizon, Y=Yes, N=No
VFI name: teste, state: up, type: multipoint, signaling: LDP
VPN ID: 1
Bridge-Domain 1 attachment circuits: Shouldn't I be able to see gig2 interface showing up here?
Neighbors connected via pseudowires:

Addresses bound to peer LDP Ident:

PE26#
I see similar outputu on the PE27`s side.
I can see that LDP is working and forming a targeted session, however for some reason I cannot see the CE interface (gig2 on both sides) as attachment circuits on the vfi.
Why?
What am I missing here?
Thanks all in advance for your time and advice.
Sincerely,
Fábio.
