Configuration Procedure; Configuring Bridge Table Entries - HPE FlexNetwork MSR Series Comware 5 Layer 2 - Wan Access Configuration Manual

•
When you configure transparent bridging over X.25, you must configure X.25 on the interface
as the link layer protocol for interface encapsulation and configure the operating mode and
datagram format of the interface. When establishing transparent bridging over X.25, you must
configure mappings between bridge addresses and X.25 addresses defined in X.121.
•
When you configure transparent bridging HDLC, you must configure HDLC as the link layer
protocol for interface encapsulation.
•
When you configure inter-VLAN transparent bridging, you must configure the encapsulation
format of the Ethernet subinterfaces and the VLAN IDs. When establishing inter-VLAN
transparent bridging, you must add the configured Ethernet subinterfaces into a bridge set.

Configuration procedure

To configure basic bridging functionalities:
Step
Enter system view.
1.
Enable bridging.
2.
Enable a bridge set.
3.
Enter interface view.
4.
Add the current interface into
5.
a bridge set.
Configure an FR-to-bridging
6.
mapping.
Configure an X.25 to
7.
bridging mapping.
Enable bridged traffic over a
8.
PVC.
For more information about ATM configuration, see "Configuring ATM."

Configuring bridge table entries

A bridge dynamically creates and maintains a bridge table based on the correlations between the
MAC addresses it has learned and the interfaces. The administrator, however, can manually
configure some bridge table entries, which will never get aged out.
The aging time of a dynamic bridge table entry refers to the lifetime of the entry before it is deleted
from the table. When the aging timer of a dynamic table entry expires, the system deletes the entry
from the table.
To configure a bridge table:
Command
system-view
bridge enable
bridge bridge-set enable
interface interface-type
interface-number
bridge-set bridge-set
fr map bridge dlci broadcast
x25 map bridge x121-address
x.121-address broadcast
interface atm { interface-number
| interface-number.subnumber }
pvc { pvc-name [ vpi/vci ] |
vpi/vci }
map bridge-group broadcast
290
Remarks
N/A
Disabled by default.
No bridge set is enabled by
default.
N/A
An interface is not in any bridge
set by default.
Optional.
This step configures transparent
bridging over FR.
Optional.
This step configures transparent
bridging over X.25.
Optional.
This step configures transparent
bridging over ATM.
If you configure both the map
bridge virtual-ethernet and map
bridge-group commands, only
the map bridge virtual-ethernet
takes effect.
