[c-nsp] ASR9000 Layer2 Access port configuration discussion

[Xu Hu]

Hi  Team,

Recently i was doing the Layer2 test in ASR9K routers, bellow is the
configuration of the test.

interface TenGigE0/0/0/0
 description to-me3600
 l2transport-----------------------------------*access port connect to
switch*

interface Bundle-Ether1.1200 l2transport
 encapsulation dot1q 1200 exact
 rewrite ingress tag pop 1 symmetric
!--------------------------------------------------*trunk port connect to
another ASR9K*

interface BVI1200
 description Vlan:BDK_CNOSS_MPBN_PS BDK_CNOSS_FW at 10.254.14.180
 vrf MEDIA
 ipv4 address 10.254.14.179 255.255.255.240-------------------*same as the
SVI interface on switch*

l2vpn
 bridge group SingTelMobile
  bridge-domain TEST
   interface TenGigE0/0/0/0
   !
   interface Bundle-Ether1.1200
   !
   routed interface BVI1200
  !

The topology is as bellow:
Switch--------(vlan1200)-----ASR9K-----(Trunk)---------ASR9K-----(vlan1200)------switch

Can anyone help to check whether the configuration is right or wrong. I use
the configuration guide from Cisco.com.

I don't quite understand why the access interface just have L2transport
configuration, is it can assign one vlan id to the access port to ASR9K.

Many thanks for your reply

Thanks and Regards,
Hu Xu
