Creating the RPR-IEEE Interface and Bridge Group
To enable the rpr-ieee interface and create the bridge group, perform the following procedure, beginning
in global configuration mode:
Command
Step 1
Router(config)# bridge irb
Step 2
Router(config)# interface
{fastethernet | gigabitethernet}
interface-number
Step 3
Router(config-if)# bridge-group
bridge-group-number
Step 4
Router(config-if)# no shutdown
Step 5
Router(config)# interface rpr-ieee 0
Step 6
Router(config-if)# rpr-ieee
protection pref jumbo
Step 7
Router(config-if)# no shutdown
Step 8
Router(config-if)# interface rpr-ieee
0 .subinterface-number
Step 9
Router(config-subif)# encap dot1q
bridge-group-number
Step 10
Router(config-subif)# bridge-group
bridge-group-number
Step 11
Router(config)# no shut
Step 12
Router(config-if)# end
Step 13
Router# copy running-config

Chapter 26 Configuring IEEE 802.17b Resilient Packet Ring
Purpose
Enables the Cisco IOS software to both route and bridge
a given protocol on separate interfaces within a single
ML-Series card.
Enters interface configuration mode to configure the
Ethernet interface that you want to include in the bridge
group.
Assigns the network interface to a bridge group.
You can safely ignore the baby giant frames
Note
warning that may appear.
Changes the shutdown state to up and enables the
interface.
Creates the rpr-ieee interface on the ML-Series card or
enters the rpr-ieee interface configuration mode. The
only valid rpr-ieee number is 0.
Enables jumbo frame capability on the RPR-IEEE
interface:
jumbo—Enables handling of frames in excess of the
standard size, up to a maximum size of 9100 bytes. A
jumbo-enabled station changes the interface MTU to
9100 bytes if all stations in the ring are jumbo enabled.
A message is generated to indicate that the ring supports
jumbo frames when all stations are configured for this
preference.
The default is no jumbo frame support.
Changes the shutdown state to up and enables the
interface.
Enters subinterface configuration mode to configure the
rpr-ieee subinterface.
Sets the encapsulation on the bridge-group to
IEEE 802.1Q.
Associates the rpr-ieee subinterface to the created bridge
group.
Enables the RPR-IEEE interface and changes the mode
from the default passthrough.
Exits to privileged EXEC mode.
(Optional) Saves the configuration changes to NVRAM.
