Reverse path forwarding
When enabling MPLS on a VE interface with reverse path forwarding, consider the following.
• The user cannot configure MPLS on a VE interface that has at least one member port enabled
with RPF strict mode. The command is rejected, and the following error message is displayed.
Brocade(config-if-e1000-4/3)# mpls-interface ve 1
Error - Cannot configure MPLS on VE with RPF strict mode port e 4/3
• The user cannot configure RPF strict mode on a port that is a member of a MPLS VE interface.
The command is rejected, and the following error message is displayed.
Brocade(config-if-e1000-4/3)# rpf-mode strict
Error: RPF: Cannot configure RPF strict mode on an MPLS VE enabled interface
• The user cannot add a port to a MPLS VE enabled VLAN when the RPF strict mode is already
enabled on the port. The command is rejected, and the following error message is displayed.
Brocade(config-vlan-100)# tagged ethernet 4/3

Port mirroring
When enabling MPLS on a VE interface with port mirroring configured, consider the following.
• The user cannot configure MPLS on a VE interface that has at least one member port enabled
with port mirroring. The command is rejected, and the following error message is displayed.
Brocade(config-mpls)# mpls-interface ve 54
Error - Can not configure MPLS tunnel on ve 54 with mirror port e4/3
• The user cannot configure a MPLS VE member port as a mirror port. The command is rejected,
and the following error message is displayed.
Brocade(config)# mirror-port e 4/3
Error: Cannot mirror a port that has MPLS VE configured
• The user cannot add a mirror port to a MPLS VE enabled VLAN. The command is rejected, and
the following error message is displayed.
Brocade(config-vlan-100)# tagged ethernet 4/3
Error - Cannot add mirror port 4/3 to MPLS VE enabled VLAN 100
