In this design it only makes sense for the SMLT Cluster nodes (Site1 & Site2) to be the OSPF
Designated Router (DR) across the two OSPF VLANs 3998 and 3999. Also we want Site1 to

always be the DR for VLAN 3998 and Site2 to always be the DR for VLAN 3999, so no BDR will
be operating on these VLANs; hence the OSPF priority on the designated DR interfaces is
increased to 100 and on every other interface it is set to 0 (interface not allowed to become DR
nor BDR).
2.2.6.3 RSMLT Configuration
RSMLT is simply enabled on the IP interfaces of both the OSPF VLANs on the IST Cluster nodes (Site1
and Site2)
Both Site1 and Site2 (only Site1 shown)
CLI
Site1:5# config vlan 3998 ip rsmlt enable
Site1:5# config vlan 3999 ip rsmlt enable
ACLI
Site1:5(config)# interface Vlan 3998
Site1:5(config-if)# ip rsmlt enable
Site1:5(config-if)# exit
Site1:5(config)# interface Vlan 3999
Site1:5(config-if)# ip rsmlt enable
Site1:5(config-if)# exit
To verify operation of OSPF and RSMLT refer to sections 3.3 and 3.4
