Configuring REP
Step 4
rep segment
segment-id
[
edge
[
no-neighbor
]
[
primary
]] [
preferred
]
Enable REP on the interface, and identify a segment number. The
segment ID range is from 1 to 1024. These optional keywords are
available.
Note
You must configure two edge ports, including one primary
edge port for each segment.
•
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) 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.
•
(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.
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.
•
(Optional) 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 5
rep stcn
{
interface
interface-id
|
segment
id-list
|
stp
}
(Optional) Configure the edge port to send segment topology change
notices (STCNs).
•
Enter
interface
interface-id
to designate a physical interface or
port channel to receive STCNs.
•
Enter
segment
id-list
to identify one or more segments to receive
STCNs. The range is 1 to 1024.
•
Enter
stp
to send STCNs to STP networks.
