To see the MAC addresses learned from a pseudowire, enter the show mac address-table dynamic
command. The example below shows output from the command.
Switch#
show mac address-table dynamic
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
100 0000.0000.0011 DYNAMIC
100 0000.0000.00bb DYNAMIC Gi0/3+Efp1
100 0000.0101.010b DYNAMIC Gi0/1
100 0000.0101.010a DYNAMIC Gi0/2
You can disable MAC address learning on a VLAN or a bridge domain.
This command disables MAC address learning on a VLAN.
Switch(config)#
no mac address-table learning vlan 100
This command disables MAC address learning on a bridge domain.
Switch(config)#
no mac address-table learning bridge-domain 100
Note
The output of the show mac address-table command does not include the port name for a pseudowire
from which a MAC address is learned.
Packet Flow in an EoMPLS Network
Figure 34-5
is an example of packet flow in an EoMPLS network. A customer port on PE1 is configured
for a per-port EoMPLS tunnel to a remote customer port on PE2. This allows the two physically
separated customer switches (A and B) connected to these ports to appear as if they are directly
connected on the same physical LAN.
The EoMPLS tunnel is configured with the IP address of Switch B and a VC ID that is associated with
the remote customer port. Switch PE1 establishes a tunnel LSP with switch PE2 by using a label
advertised with LDP by Router A, which is connected to switch PE1. Switch PE1 then establishes a
targeted LDP session to switch PE2 to advertise the virtual-connection label associated with the VC ID.
When switch PE2 is configured with the EoMPLS tunnel, it also establishes a targeted LDP session to
advertise the virtual-connection label it associated to the VC ID. This establishes an EoMPLS tunnel
between switch PE1 and switch PE2.
