WAN Interfaces
Bundle Configuration
Configuration of an interface bundle is required for use of any of the Secure Router WAN
interfaces. Multiple physical interfaces may be linked to a single interface bundle; multi-link
protocols, including MLPPP and Multilink Frame Relay, make use of NxT1 interfaces to create
single logical interfaces.
The interface bundle specifies the physical connection(s) to be linked, an encapsulation
protocol (Layer 2) and, optionally, Layer 3 parameters.
Fractional T1
The following example creates a 384 Kbps fractional T1 bundle utilizing DS0s 1-3 and 8-10 of
T1 number 3.
Configure a Fractional T1 HDLC Bundle
SR/configure> interface bundle demo 1
SR/configure/interface/bundle> link t1 3:1-3,8-10
SR/configure/interface/bundle> encap hdlc
SR/configure/interface/bundle> ip addr 10.1.1.1 255.255.255.252
SR/configure/interface/bundle> exit
T1
The following example creates a 1536 Kbps T1 bundle utilizing T1 number 4. This bundle uses
IP unnumbered.
Configure a T1 PPP Bundle
SR/configure> interface bundle demo2
SR/configure/interface/bundle> link t1 4
SR/configure/interface/bundle> encap ppp
SR/configure/interface/bundle> ip unnumbered ethernet0
SR/configure/interface/bundle> exit
