Considerations when Migrating from
SMLT to SPB
• Switch Clustering (SMLT)
• IP Routing – Global Routing Table
• In-band Network Management using Global
Routing Table
• End-to-end Layer 2 VLANs
• IPVPN-Lite
• Minimising network disruption during migration

February 26-28, 2013 | Orlando, FL
Migrating from SMLT to SPB
• Typical Inception
design use SMLT/
RSMLT with:
• Target design uses
SPB and must
migrate:
• End-to-end L2 VLANs
• IP Routing
• IPVPN-Lite
©2013 Avaya Inc. All rights reserved
• L2 VSNs
• Native IP shortcuts
• IPVPN-Lite over SPB
or
Optional

Deploy SPB infrastructure in parallel

Avoiding Migration Loops !!!

SPB Core
I-SID 12990010
• There is no Spanning Tree over SMLT
• There is no Spanning Tree over SPB L2VSNs
• It would be quite easy to create a loop between old and new
transport
• To prevent this from happening ERS 8800 enforces a consistency
check:
• An ISID cannot be assigned to a VLAN if that VLAN exists on ISIS
interfaces

Migrating Extended VLAN 10
Step #1
SMLT Core
VLAN 10
Edge VLAN 10
Edge VLAN 10
SPB Core
I-SID 12990010
• First delete VLAN 10 on uplinks to Core
• Traffic on VLAN 10 will be interrupted

Migrating Extended VLAN 10
Step #2
SMLT Core
VLAN 10
Edge VLAN 10
Edge VLAN 10
SPB Core
I-SID 12990010
• Re-configure VLAN 10 at the Edge to use SPB L2 VSN
• vlan 10 i-sid 12990010
• Traffic on VLAN 10 will now resume almost immediately

Migrating Extended VLAN 10
Step #3
SMLT Core
VLAN 10
Edge VLAN 10
Edge VLAN 10
SPB Core
I-SID 12990010
• VLAN 10 in the SMLT Core is no longer needed
• Verify that no more traffic is using it
• Then delete it

Migrating GRT IP Routing
from OSPF to IS-IS
OSPF + RSMLT
10.0.1.0/24
10.0.2.0/24
IS-IS
•
•

•
There is no risk of loops here
There is no traffic interruption during migration
Simply enable SPB Native IP shortcuts
IS-IS routes, by default, have a higher pref (7) than OSPF routes (20)
The default IS-IS pref must be temporarily increased beyond OSPF to
ensure that IP routes are correctly learned by IS-IS before actually
switching over to IS-IS
Once satisfied that IS-IS routes are good, then restore IS-IS default pref to
switch over to IS-IS

• At this point there should be no more VLANs running on
the Core SMLT Cluster
• After verifying this
• Decommission SMLT and the IST on the Core nodes
• The Core MLT instances can also be deleted
