Activating SPB
Once the network is upgraded the following minimum steps must be followed before any services can be
provisioned. SPB leverages the usage of default parameters and link metrics, system-id values etc., to
minimize the number of configurations steps. Customers that desire to use non default parameters should
do so in accordance with the configuration and engineering guidelines.
ERS 8800
o
Activating SPB infrastructure reserves 600 multicast group ID (MGIDs) for SPB operation
on the ERS 8800. This is in addition to any MGIDs that may be used for VLANs and IP
multicast services. The “show sys mgid-usage” command should be used to check if the
MGIDs required for SPB are available.
o
If the ERS 8800 is running in STG mode, verify that STG-63 is not current in use. SPB will
use this STG.
o
If running in MSTP mode – verify that MSTI-62 is not currently in use. SPB will use this
MSTI.
VSP 9000
o
Activating SPB infrastructure reserves 100 multicast group ID (MGIDs) for SPB operation
on the VSP 9000.
All models
o
SPB is not supported if the switch is in RSTP mode. Note that there is no reason to use
the RSTP mode since it provides a sub-set of the functionality of MSTP mode and MSTP
mode is able to operate in RSTP mode if it sees adjacent switches sending RSTP BPDUs.
Identify two VLAN-ids to be used as B-VLANs by SPB, primary and secondary B-VLAN
o
Note, the same primary and secondary VLAN IDs must be provisioned on all SPB
enabled switches so that all SPB bridges will load balance traffic accordingly
o
The IS-IS adjacencies will not come up if there is a discrepancy in the B-VLAN ids
configuration between 2 nodes.
o
The Primary VLAN IDs is also used on all IS-IS messages
Enable SPB globally.
Assign a unique nickname to each switch.
o
An alarm will be logged if a duplicate nickname is provisioned in the network
Assign a common Area ID
o
Note, the same Area ID must be provisioned on all SPB enabled switches in the same
domain
Assign a unique IS-IS system-name to each switch. While this is not strictly required – it will
greatly aid in validating connectivity and when troubleshooting.
o
If the IS-IS sys-name is not provisioned, by default, the global system name is used as
the IS-IS sys-name. If you do wish to set the IS-IS sys-name, it must be set to a value
different than global system name.
If configuring an IST switch, configure the system-id of the IST peer.
Identify all the intended NNIs and configure and enable IS-IS on these ports (or MLTs).
