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
 Minimizing network disruption during migration

Migrating from SMLT to SPB
 Typical Inception design uses
SMLT/RSMLT with:
 End-to-end L2 VLANs
 IP Routing
 IPVPN-Lite (VRF)
© 2014 Avaya Inc. Avaya – Confidential & Proprietary
Do not duplicate, publish or distribute further without the express written permission of Avaya.
 Target design uses SPB and
must migrate:
 L2 VSNs
 Native IP shortcuts
 IPVPN-Lite over SPB
or ideally
 SPB L3 VSNs

Avoiding Migration Loops !!!

Broadcast
Edge VLAN 10
Edge VLAN 10
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

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

Step 2

 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

 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

10.0.2.0/24
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
