Chapter 16 Fragmenting and Interleaving Real-Time and Nonreal-Time Packets
Multilink PPP-Based Link Fragmentation and Interleaving
Example 16-4
shows how to add Frame Relay links to a MLP bundle. In the example, MLP is enabled
on the Multilink 20009 interface and on the virtual template named Virtual-Template 209. The
service-policy named voip is applied to the Multilink 20009 interface. Virtual-Template 209 is applied
to DLCI 18 on the serial subinterface 3/0/1.1.

Step 4
Router(config-if)#
encapsulation frame-relay
[
ietf
|
cisco
]
Specifies Frame Relay as the interface encapsulation type.
(Optional)
ietf
sets the encapsulation method to comply with
the Internet Engineering Task Force (IETF) standard (RFC
1490). Use this keyword when connecting to another
vendor’s equipment across a Frame Relay network.
(Optional)
cisco
indicates to use Cisco’s own encapsulation,
which is a 4-byte header, with 2 bytes to identify the data-link
connection identifier (DLCI) and 2 bytes to identify the
packet type. This is the default encapsulation type.
Step 5
Router(config-if)#
interface serial
slot
/
module
/
port
.
subinterface
point-to-point
Configures or modifies the subinterface you specify. Enters
subinterface configuration mode.
Step 6
Router(config-subif)#
frame-relay
interface-dlci
dlci
ppp
virtual-template-name
Assigns a data-link connection identifier (DLCI) to the
Frame Relay subinterface and applies a virtual template
configuration for a PPP session.
dlci
is a number that identifies the connection. This number
is specific to the local subinterface.
ppp
enables the circuit to use PPP in Frame Relay
encapsulation.
virtual-template-name
specifies which virtual template
interface to apply the PPP connection to.
Step 7
Router(config-subif)#
service-policy
{
input
|
output
}
policy-map-name
Applies the service policy you specify to the subinterface.
input
indicates to apply the service policy to the traffic on the
inbound interface.
output
indicates to apply the service policy to the traffic on
the outbound interface.
Note
For QoS policies containing the
bandwidth
,
priority
,
random-detect
,
queue-limit
, and
shape
commands, you must specify the
output
keyword.
The router ignores these commands when you use
them with the
input
keyword.
policy-map-name
is the name of the policy map.
