Configuring Resilient Ethernet Protocol (REP)

Configuring the REP Administrative VLAN

To avoid the delay introduced by relaying messages in software for link-failure or VLAN-blocking notification during load balancing, REP floods packets at the hardware flood layer (HFL) to a regular multicast address. These messages are flooded to the whole network, not just the REP segment. You can control flooding of these messages by configuring an administrative VLAN for the whole domain.

Follow these guidelines when configuring the REP administrative VLAN:

•If you do not configure an administrative VLAN, the default is VLAN 1.

•There can be only one administrative VLAN on a router and on a segment. However, this is not enforced by the software.

•For VLB to work, rep platform vlb has to be configured on every Cisco ASR 901router participating in the segment.

Complete the following steps to configure the REP administrative VLAN:

SUMMARY STEPS

1.enable

2.configure terminal

3.rep admin vlan vlan-id

4.end

5.show interface [interface-id]rep [detail]

6.copy running-config startup config

DETAILED STEPS

	Command		Purpose
Step 1
	enable		Enables privileged EXEC mode.
			• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal		Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3
	rep admin vlan vlan-id		Configures a REP administrative VLAN.
			• Specify the administrative VLAN. The range is
	Example:		1–4094. The default is VLAN 1.
	Router(config)# rep admin vlan 1
Step 4
	end		Returns to privileged EXEC mode.
	Example:
	Router(config)# end
