Configuring Resilient Ethernet Protocol (REP)

	Command	Purpose
Step 5
	show interface [interface-id]rep [detail]	Displays the REP configuration and status for a specified
		interface.
	Example:	• Enter the physical Layer 2 interface or port channel
	Router# show interface gigabitethernet0/1 rep	(logical interface) and the optional detail keyword, if
	detail	desired.
Step 6
	copy running-config startup config	(Optional) Saves your entries in the router startup
		configuration file.
	Example:
	Router# copy running-config startup config

Configuring REP Interfaces

For REP operation, you need to enable it on each segment interface and identify the segment ID. This step is required and must be done before other REP configuration. You must also configure a primary and secondary edge port on each segment. All other steps are optional.

Complete these steps to enable and configure REP on an interface:

SUMMARY STEPS

1.enable

2.configure terminal

3.interface interface-id

4.service instance <instance-id>ethernet encap dot1q <admin-vlan>rewrite ingress tag pop 1 symmetric bridge-domain <bd-id>

5.rep segment segment-id[edge [no-neighbor] [primary]] [preferred]

6.rep lsl-retriesnumber-of-retries

7.rep stcn {interface interface-id segment id-list stp}

8.rep platform vlb segment segment-idvlan {vlan-listall}

9.rep block port {id port-id neighbor-offset preferred} vlan {vlan-list all}

10.rep preempt delay seconds

11.rep lsl-age-timer value

12.end

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

14.show rep topology [segment segment-id] [archive] [detail]

15.copy running-config startup config
