Fig 1-6 Dot1q-tunnel based Internetworking
mode
As shown in above, after being enabled on the user port, dot1q-tunnel assigns each user
an SPVLAN identification (SPVID). Here the identification of user is 3. Same SPVID should be
assigned for the same network user on different PEs. When packet reaches PE1 from CE1, it
carries the VLAN tag 200-300 of the user internal network. Since the dot1q-tunnel function is
enabled, the user port on PE1 will add on the packet another VLAN tag, of which the ID is the
SPVID assigned to the user. Afterwards, the packet will only be transmitted in VLAN3 when
traveling in the ISP internet network while carrying two VLAN tags (the inner tag is added when
entering PE1, and the outer is SPVID), whereas the VLAN information of the user network is
open to the provider network. When the packet reaches PE2 and before being forwarded to
CE2 from the client port on PE2, the outer VLAN tag is removed, then the packet CE2 receives
is absolutely identical to the one sent by CE1. For the user, the role the operator network plays
between PE1 and PE2, is to provide a reliable layer-2 link.
The technology of Dot1q-tuunel provides the ISP internet the ability of supporting many
client VLANs by only one VLAN of theirselves. Both the ISP internet and the clients can
configure their own VLAN independently.
It is obvious that, the dot1q-tunnel function has got following characteristics:
Applicable through simple static configuration, no complex configuration or
maintenance to be needed.
Operators will only have to assign one SPVID for each user, which increases the
number of concurrent supportable users; while the users has got the ultimate
freedom in selecting and managing the VLAN IDs (select within 1~4096 at users’
will).
The user network is considerably independent. When the ISP internet is upgrading
their network, the user networks do not have to change their original configuration.
Detailed description on the application and configuration of dot1q-tunnel will be provided
in this section.
