[inet-admins] EoMPLS help...

[blny@xxxxxx]

Sorry еще раз... ;)

Я просто тред затеял - потому как не савсем догоняю следующую вешь..

Вот кусок из доки 

http://www.cisco.com/univercd/cc/td/doc/product/core/cis7600/software/122sx/swcg/pfc3mpls.htm#wp1318682

Configuring EoMPLS VLAN Mode for SUP720-3BXL

- VLAN mode. 

Transports Ethernet traffic from a source 802.1Q VLAN to a
destination 802.1Q VLAN through a single VC over an MPLS network. VLAN
mode uses VC type 5 as default (no dot1q tag) and VC type 4 (transport
dot1 tag) if the remote PE does not support VC type 5 for subinterface
(VLAN) based EoMPLS.

- Port mode. 

Allows all traffic on a port to share a single VC across an
MPLS network. Port mode uses VC type 5. 

Собственно то что я хотел сделать - это EoMPLS VLAN mode c VC type 4
(transport dot1 tag)

Но как ?! 

Берем конфигурим VLAN mode EoMPLS по доке

interface GigabitEthernet1/2.3620
 description ** MPLS VPN L2 test
 encapsulation dot1Q 3620
 mpls l2transport route 10.30.0.69 3620
!
interface GigabitEthernet1/2.3621
 description ** MPLS VPN L2 test
 encapsulation dot1Q 3621
 xconnect 10.30.0.69 3621 encapsulation mpls
       
GL-1#sh mpls l2transport vc

Local intf     Local circuit        Dest address    VC ID      Status
-------------  -------------------- --------------- ----------
----------
Gi1/2.3620     Eth VLAN 3620        10.30.0.69      3620       UP
Gi1/2.3621     Eth VLAN 3621        10.30.0.69      3621       UP

Видим обещанный VC type 5 - по default

GL-1#remote command switch sh mpls l2transport vc 3620 de

Local interface: GigabitEthernet1/2, Eth VLAN 3620
  Destination address: 10.30.0.69, VC ID: 3620
    VC status: receive UP, send UP
    VC type: receive 5, send 5
  Tunnel label: imp-null, next hop point2point
    Output interface: Tu1, imposed label stack {7090 171}
    MPLS VC label: local 16, remote 171
  Linecard VC statistics:
    packet totals:  receive: 0  send: 0
    byte totals:  receive: 0  send: 0
    packet drops:  receive: 0  send: 0
  Control flags:
    receive 1,  send: 11
    in_vlan[3620] table_id[261]
    tcam_addr[0x56] adj_addr[458752]

Как собственно сделать VC typе 4 ?

При этом Port mode - с тем же VC type 5 - VLAn tag передает

Свихнусь скоро ;((
