Something wrong in the "BASIC" VPLS configuration...

[Mario Rosi]

Hi, 

i configured on two PEs the VPLS with this configuration (IOS XE):

PE1:

interface Loopback0
description IGP-mBGP-MPLS Backbone Interface
ip address 5.100.237.8 255.255.255.255
no ip redirects
no ip proxy-arp

!

...

l2vpn vfi context BD100
vpn id 100
autodiscovery bgp signaling ldp

!

...

interface GigabitEthernet5
no ip address
negotiation auto
cdp enable
no mop enabled
no mop sysid
service instance 1 ethernet
encapsulation untagged
bridge-domain 100
!
...

router bgp 10
bgp log-neighbor-changes
neighbor 5.100.237.20 remote-as 10
neighbor 5.100.237.20 update-source Loopback0
!
address-family l2vpn vpls
neighbor 5.100.237.20 activate
neighbor 5.100.237.20 send-community both
exit-address-family
!

...

PE2

interface Loopback0
description IGP-mBGP-MPLS Backbone Interface
ip address 5.100.237.20 255.255.255.255
no ip redirects
no ip proxy-arp

!

l2vpn vfi context BD100
 vpn id 100
 autodiscovery bgp signaling ldp

!

...

interface GigabitEthernet4
no ip address
negotiation auto
cdp enable
no mop enabled
no mop sysid
service instance 1 ethernet
encapsulation dot1q 2
rewrite ingress tag pop 1 symmetric
snmp ifindex persist
bridge-domain 100
!

...

router bgp 10
bgp log-neighbor-changes
neighbor 5.100.237.8 remote-as 10
neighbor 5.100.237.8 update-source Loopback0
!
address-family l2vpn vpls
neighbor 5.100.237.8 activate
neighbor 5.100.237.8 send-community both
exit-address-family
!

I know that i'm missing something but i don't know what, anyway, it doesn't work:

MPLS_A#sh l2vpn service name BD100
Legend: St=State XC St=State in the L2VPN Service Prio=Priority
UP=Up DN=Down AD=Admin Down IA=Inactive
SB=Standby HS=Hot Standby RV=Recovering NH=No Hardware
m=manually selected

Interface Group Encapsulation Prio St XC St
--------- ----- ------------- ---- -- -----
VPLS name: BD100, State: DN
pw100002 BD100(VFI) 0 DN DN
pw100003 core_pw 5.100.237.20:100(MPLS) 0 DN DN

MPLS_A#sh l2vpn vfi name BD100
Legend: RT=Route-target, S=Split-horizon, Y=Yes, N=No

VFI name: BD100, state: down, type: multipoint, signaling: LDP
VPN ID: 100, VPLS-ID: 10:100
RD: 10:100, RT: 10:100,
Local attachment circuits:
Pseudo-port interface: pseudowire100002
Interface Peer Address VC ID Discovered Router ID S
pseudowire100003 5.100.237.20 100 5.100.237.20 Y

...then, if i adopt another configuration template:

l2 vfi BD200 autodiscovery
vpn id 200
bridge-domain 200

!

...

interface GigabitEthernet6
no ip address
negotiation auto
cdp enable
no mop enabled
no mop sysid
service instance 1 ethernet
encapsulation dot1q 1,3-5
bridge-domain 200
!
!

and the same on the other PE, it works.

MPLS_A#sh l2vpn service name BD200
Legend: St=State XC St=State in the L2VPN Service Prio=Priority
UP=Up DN=Down AD=Admin Down IA=Inactive
SB=Standby HS=Hot Standby RV=Recovering NH=No Hardware
m=manually selected

Interface Group Encapsulation Prio St XC St
--------- ----- ------------- ---- -- -----
VPLS name: BD200, State: UP
pw100004 BD200(VFI) 0 UP UP
pw100005 core_pw 5.100.237.20:200(MPLS) 0 UP UP

MPLS_A#sh l2vpn vfi name BD200
Legend: RT=Route-target, S=Split-horizon, Y=Yes, N=No

VFI name: BD200, state: up, type: multipoint, signaling: LDP
VPN ID: 200, VPLS-ID: 10:200
RD: 10:200, RT: 10:200,
Bridge-Domain 200 attachment circuits:
Pseudo-port interface: pseudowire100004
Interface Peer Address VC ID Discovered Router ID S
pseudowire100005 5.100.237.20 200 5.100.237.20 Y

May you help me finding where is the missing part of coniguration that doens't let VPLS basic configuration to work?

Thanks,

Mario

Solved on my own! :)

I just adopted the new configuration template via "l2vpn..."

Here below the configuration that is working end2end

l2vpn vfi context BD100

 vpn id 100

 autodiscovery bgp signaling bgp (or ldp)

!
