Nexus 7009 EoMPLS L2VPN for VLAN Trunk

Hi,

Problem: Howto configure EoMPLS L2VPNs on Nexus7000 for Layer2 VLAN
Trunking ?

   I have TWO HW and SW identical Nexus 7009 with Sup2E running under
NX-OS 6.2(2a) with HW Modules:

Mod  Ports  Module-Type                         Model              Status
---  -----  ----------------------------------- ------------------
1    0      Supervisor Module-2                 N7K-SUP2E     active *
2    0      Supervisor Module-2                 N7K-SUP2E     ha-standby
3    24     10 Gbps Ethernet Module             N7K-M224XP-23L     ok
4    24     10 Gbps Ethernet Module             N7K-M224XP-23L     ok
5    48     1000 Mbps Optical Ethernet XL Modul N7K-M148GS-11L     ok

Both Nexus7009 are running in an MPLS Backbone using L3VPNs for
different customergroups.

The hostname and Loopback Adresses of the two Nexus 7009 are listed below:

1.st Router
hostname: N7K-R1-gw
Loopback0 Address: 172.17.127.110
Interface: Ethernet 3/24

2.nd Router
hostname: N7K-R2-gw
Loopback0 Address: 172.17.127.5
Interface: Ethernet 3/24

Both Nexus7009 are connected via Ethernet Interfaces Eth3/24
to our MPLS Backbone; Interfaces are configured with:
mpls ip
mtu 9216


I need to configure a Point-to-Point L2VPN (Ethernet over MPLS) between
the two Nexus 7009 in oder to trunk several VLans over this L2VPN. I
tried the following Configuration:

Configuration on Host: N7k-R1-gw:
=================================
feature-set mpls
feature mpls l2vpn

l2vpn
feature evc

l2vpn xconnect context to_N7K-R2-gw
  member Ethernet5/25
  member pseudowire10

interface pseudowire10
  neighbor 172.17.127.5 10
  encapsulation mpls
  mtu 9216

interface Ethernet5/25
  switchport
  switchport mode trunk
  switchport trunk allowed vlan 410,414
  mtu 9216
  no shutdown

Ethernet5/1 is down (Remote port is down in L2VPN service)

N7k-R1-gw# sh int eth5/1
Ethernet5/25 is down (SFP not inserted)
admin state is up, Dedicated Interface

Any ideas whats going wrong ? Maybe I do not understand how it
works.

Thanks in advance Manfred

HI Manfred, Can you configure

HI Manfred,

 

Can you configure the attachment circuits(e5/1 and e5/25) in either vlan or port mode?
