IP Over ATM and LANE Creating an Emulated LAN
connected by a logical full-mesh topology. In this case, the term “logical” means only that all LNNI switches
participating within a particular domain should be able to reach each other. Typically, a full-mesh topology is satisfied
by PNNI, and does not require all LES/BUS switches to be directly connected.
The following is an example of configuring a distributed LNNI LES/BUS on SW3. This example continues from the
example above — Two LECS’ are running redundantly for ELAN 1 (
elan1 ).
1. On switch SW3, enter the stop lecs command on the switch to contain the LES/BUS. This is done
to make sure the LECS is not running on this switch.
SW3 # stop lecs
Confirm(y/n)?:y
NOTICE - 'LECS' ***** LECS shutdown *****
SW3 #
2. On switch SW3, use the add buselan command to associate this switches BUS with the ELAN on
switches SW1 and SW2 ( elan1 ).
SW3 # add buselan
ELANNumber(0) : 1
ELANName(ELAN001) : elan1
ConnectMethod(SVC) :
ELANType(802.3) :
Multipoint(YES) :
MTU(1516) :
ErrorLogEnable(NO) :
MinimumTDEnable(NO) :
SW3 #
3. On switch SW3, use the add leselan command to associate this switches LES with the ELAN on
switches SW1 and SW2 ( elan1 ).
SW3 # add leselan
ELANNumber(0) : 1
ELANName(ELAN001) : elan1
ConnectMethod(SVC) :
ELANType(802.3) :
Multipoint(YES) :
MTU(1516) :
ErrorLogEnable(NO) :

4. On switch SW3, use the stop les command to stop the LES/BUS service
SW3 # stop les
STOPPING LES/BUS
Confirm(y/n)?:y
NOTICE - 'ZLESSRV' ***** LES shutdown *****
SW3 #
5. On switch SW3, use the set lnniinfo to configure LNNI
SW3 # set lnniinfo
LECSID(-1) : — Accept -1, there will be no LECS on this switch
SW3 #
