[c-nsp] ME3600 - SVI's + Service Instances

[Scott Miller]

We use them in a pseudowire/service instance configuration:

cisco ME-3800X-24FS-M

!
interface GigabitEthernet0/1
 description NNI Directly Connected to Carrier
 switchport trunk allowed vlan none
 switchport mode trunk
 mtu 1586

and then service instances which connect back to the original PE via
pseudowire

 service instance 1000 ethernet
  encapsulation dot1q 2000
  rewrite ingress tag pop 1 symmetric
  l2protocol tunnel
  xconnect x.x.x.x 1000 encapsulation mpls
   mtu 1586
 !
