Configuring the REP Administrative VLAN: Example

This example shows how to configure the administrative VLAN as VLAN 100.

Router# configure terminal

Router(config)# rep admin vlan 100

Router(config-if)# end

Configuring a REP Interface: Example

This example shows how to configure an interface as the primary edge port for segment 1, to send Spanning Tree Topology Changes Notification (STCNs) to segments 2 through 5, and to configure the alternate port as the port with port ID 0009001818D68700 to block all VLANs after a preemption delay of 60 seconds after a segment port failure and recovery.

Router# configure terminal

Router(config)# interface gigabitethernet0/1

Router(config-if)#rep segment 1 edge primary

Router(config-if)#rep stcn segment 2-5

Router(config-if)#rep block port 0009001818D68700 vlan all

Router(config-if)#rep preempt delay 60

Router (config-if)#rep lsl-age-timer 6000

Router(config-if)# end

This example shows how to configure the same configuration when the interface has no external REP neighbor:

Router# configure terminal

Router(conf)# interface gigabitethernet0/1

Router(config-if)#rep segment 1 edge no-neighbor primary

Router(config-if)#rep stcn segment 2-5

Router(config-if)#rep block port 0009001818D68700 vlan all

Router(config-if)#rep preempt delay 60

Router(config-if)#rep lsl-age-timer 6000

Figure 6 shows how to configure the VLAN blocking configuration. The alternate port is the neighbor with neighbor offset number 4. After manual preemption, VLANs 100 to 200 are blocked at this port and all other VLANs are blocked at the primary edge port E1 (Gigabit Ethernet port 0/1).
