Chapter 26 Configuring IEEE 802.17b Resilient Packet Ring
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 Purpose
Step 1 Router(config)# bridge irb Enables the Cisco IOS software to both route and bridge
a given protocol on separate interfaces within a single
ML-Series card.
Step 2 Router(config)# interface
{fastethernet | gigabitethernet}
interface-number
Enters interface configuration mode to configure the
Ethernet interface that you want to include in the bridge
group.
Step 3 Router(config-if)# bridge-group
bridge-group-number
Assigns the network interface to a bridge group.
Note You can safely ignore the baby giant frames
warning that may appear.
Step 4 Router(config-if)# no shutdown Changes the shutdown state to up and enables the
interface.
Step 5 Router(config)# interface rpr-ieee 0 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.
Step 6 Router(config-if)# rpr-ieee
protection pref jumbo
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.
Step 7 Router(config-if)# no shutdown Changes the shutdown state to up and enables the
interface.
Step 8 Router(config-if)# interface rpr-ieee
0 . subinterface-number
Enters subinterface configuration mode to configure the
rpr-ieee subinterface.
Step 9 Router(config-subif)# encap dot1q
bridge-group-number
Sets the encapsulation on the bridge-group to
IEEE 802.1Q.
Step 10 Router(config-subif)# bridge-group
bridge-group-number
Associates the rpr-ieee subinterface to the created bridge
group.
Step 11 Router(config)# no shut Enables the RPR-IEEE interface and changes the mode
from the default passthrough.
Step 12 Router(config-if)# end Exits to privileged EXEC mode.
Step 13 Router# copy running-config
startup-config
(Optional) Saves the configuration changes to NVRAM.
