■
When configuring transparent bridging over FR, you need to configure FR on
the corresponding interface as the link layer protocol for interface
encapsulation, configure the FR interface type (optional, DTE by default) and
configure a virtual circuit. When establishing transparent bridging over FR, you
need to configure mappings between bridge addresses and data link
connection identifier (DLCI) addresses.
■
When configuring transparent bridging over X.25, you need to configure X.25
on the corresponding interface as the link layer protocol for interface
encapsulation and configure the work mode and datagram format of the
interface. When establishing transparent bridging over X.25, you need to
configure mappings between bridge addresses and X.25 addresses defined in
X.121.
■
When configuring transparent bridging HDLC, you need to configure HDLC as
the link layer protocol for interface encapsulation.
■
When configuring inter-VLAN transparent bridging, you need to configure the
encapsulation format of the Ethernet sub-interfaces and the corresponding
VLAN IDs. When establishing inter-VLAN transparent bridging, you need to add
the configured Ethernet sub-interfaces into a bridge set.
Follow these steps to configure basic bridging functionalities
For more information about ATM configuration, refer to “ATM and DSL Interface
Configuration” on page 71 .

If you configure both the map
bridge virtual-ethernet and
map bridge-group commands,
only the map bridge
virtual-ethernet takes effect.
