MSTP support for PBB
12
High availability
MSTP supports MP switchover and hitless software upgrade. When an MSTP root bridge undergoes
MP switchover and hitless upgrade, there will be no break in transmission of the MSTP BPDU from
it during reboot of the line cards. Due to this, there will be no re-convergence of the topology and no
disruption in traffic.
MSTP PBB with multi region feature also supports MP switchover and hitless software upgrade.
There will be no traffic disruption during an upgrade.
MSTP PBB Configuration Commands
MSTP-region
To configure multiple MSTP regions on a single bridge to represent different bridging domains, use
the MSTP-region command. This command is available only in config mode.
All the existing MSTP commands can be executed from this submode.
Brocade(config)#mstp-region 1
Brocade(config-mstp-region-1)# mstp-region ?
Syntax: [no] mstp-region region-id
The acceptable range for this command is 1 to 10.
Executing the mstp-region command with [no] will delete all the configurations that are configured
under the region submode.
MSTP Instance Mapping
To configure Regular VLANs or VPLS VLANs mapped to an MSTP instance in a PB or PBB network,
use the following command options.
Syntax: [no] mstp-region instance instance-id vlan vlan-id
Syntax: [no] mstp-region instance instance-id vlan vlan-id to vlan-id
Syntax: [no] mstp-region instance instance-id vlan-group group-id
For the Brocade MLX series and Brocade NetIron XMR
On the Brocade MLX series and Brocade NetIron XMR, use the following commands to configure
VPLS VLANs mapped to an MSTP instance.
Syntax: [no] mstp-region instance instance-id vpls vpls-id vlan vlan-id
Syntax: [no] mstp-region instance instance-id vpls vpls-id vlan vlan-id to vlan-id
For the Brocade NetIron CER and Brocade NetIron CES
On the Brocade NetIron CER and Brocade NetIron CES, use the following command to configure
VPLS VLANs mapped to an MSTP instance.
Syntax: [no] mstp-region instance instance-id esi esi-name vlan vlan-id
