Chapter 14 Configuring Resilient Ethernet Protocol
Configuring Resilient Ethernet Protocol (REP)
Step 5
rep segment segment-id [edge
[no-neighbor] [primary]] [preferred]
Example:
Router(config-if)# rep segment 1 edge
preferred
Enables REP on the interface, and identifies a segment number. The
segment ID range is from 1 to 1024.
Note You must configure two edge ports, including one primary
edge port for each segment.
These optional keywords are available.
• Enter edge to configure the port as an edge port. Entering edge
without the primary keyword configures the port as the
secondary edge port. Each segment has only two edge ports.
• (Optional) Enter no-neighbor to configure a port with no
external REP neighbors as an edge port. The port inherits all
properties of edge ports, and you can configure them the same as
any edge port.
• On an edge port, enter primary to configure the port as the
primary edge port, the port on which you can configure VLAN
load balancing.
Note Although each segment can have only one primary edge port,
if you configure edge ports on two different switches and
enter the primary keyword on both switches, the
configuration is allowed. However, REP selects only one of
these ports as the segment primary edge port. You can
identify the primary edge port for a segment by entering the
show rep topology privileged EXEC command.
• Enter preferred to indicate that the port is the preferred alternate
port or the preferred port for VLAN load balancing.
Note Configuring a port as preferred does not guarantee that it
becomes the alternate port; it merely gives it a slight edge
among equal contenders. The alternate port is usually a
previously failed port.
Step 6
rep lsl-retries number-of-retries
Example:
Router(config-if)# rep lsl-retries 4
Use the rep lsl-retries command to configure the REP link status
layer (LSL) number of retries before the REP link is disabled.
Step 7
rep stcn {interface interface-id |
segment id-list | stp}
Example:
Router(config-if)# rep stcn segment 2-5
(Optional) Configures the edge port to send segment topology
change notices (STCNs).
• Enter interface interface-id to designate a physical interface to
receive STCNs.
• Enter segment id-list to identify one or more segments to receive
STCNs. The range is from 1–1024.
• Enter stp to send STCNs to STP networks.
