Binding Multiple Carrier Lines to a Frame Relay Interface

On the ProCurve Secure Router, links are always defined by the Data Link
Layer rather than the Physical Layer. You bind a physical interface to a logical
interface to grant the Data Link Layer protocol access to the physical media
over which to transmit data. This way of defining links makes configuring
MLFR easy: you simply bind more than one carrier line to the same Frame
Relay interface.
You can bind as many lines to the Frame Relay interface as are installed on
the router. The ProCurve Secure Router 7102dl provides up to 4 E1- or T1-
carrier lines. The ProCurve Secure Router 7203dl provides up to 12 E1- or T1-
carrier lines, depending on the modules that you purchase.
You should have already configured the physical interfaces. If you have not,
see the Basic Management and Configuration Guide, Chapter 4: Configur-
ing E1 and T1 Interfaces for instructions. To bind the physical interfaces to
the Frame Relay interface, you need this information:
type of carrier line (E1 or T1)
dl module slot for the carrier line's module
port number for the interface to which the line connects
TDM group number
The TDM group number defines the range of channels used by an E1- or T1-
carrier line. Lines that will be aggregated can use the same or a different TDM
group number, but these lines must use the same number of channels.
If you bind a physical interface to the Frame Relay interface and then enable
multilink, the non-multilink binding is removed from the interface. You will
have to rebind the original line as well as the new lines to the Frame Relay
interface.
You can enter the bind command either from the global or the Frame Relay
interface configuration mode context. Enter the command for each carrier
line that you want to bundle:
Syntax: bind <bind number> [e1 | t1] <slot>/<port> <tdm group number> frame-relay
<interface number>
Each physical interface should be bound to the Frame Relay interface with a
unique bind number. For example, you might enter:
ProCurve(config)# bind 1 e1 1/1 1 fr 1
ProCurve(config)# bind 2 e1 1/2 1 fr 1
ProCurve(config)# bind 3 e1 2/1 1 fr 1
