Example Network Scenarios

The following examples illustrate parameter values that typically need to be set for different network
scenarios.
4.5.6.1 IP over ATM, Routed
The following explains how to set up Routed protocols over ATM PVCs using LLC or VCMux
encapsulation.
When using PVCs, a user has two ways of carrying multiple protocols over ATM:
Virtual circuit (VC) based multiplexing – The user defines one PVC per protocol. This uses
!
more VCs than LLC encapsulation but reduces overhead because a header is not necessary.
Logical Link Control (LLC) Encapsulation – The user multiplexes multiple protocols over a
!
single ATM VC. The protocol of a carried data unit (PDU) is identified by prefixing the PDU
with an LLC header.
PVC 0/38 is used between HL950 and DSLAM.
The HL950 configuration (refer to Figure 27):
__________________________________________________________________________________
WIF 2x SHDSL Configuration:
HL950> start interface wan shdsl
Ethernet Configuration:
HL950> set interface data Ethernet:if=eth0, dmode=routed, type=lan,
ip=10.2.20.1, mask=255.255.255.0;
HL950> start interface data Ethernet:if=eth0;
ATM VCC Configuration:
HL950> add interface atm vcc:name=dslam, type=aal5, vcc=0/38, srvtype=ubr;
WAN Configuration:
HL950> add interface data wanaal5
