Does anyone have any experience with configuring multiple spanning tree instances between C5 switches and the x670.

I have mstp running between two x670s, but want to integrate with a C5. I can supply configs.

Many thanks

ANd on the black side:

#port
set port vlan ge.1.2 2
set port vlan ge.1.3 2

#spantree
set spantree mstcfgid cfgname 'region1'
set spantree msti sid 1 create
set spantree msti sid 2 create

set spantree mstmap 2 sid 2
set spantree priority 8192 0
set spantree priority 8192 1

I don't know if this is still relevant, but the VLAN to instance mapping of the EXOS configuration does not match that of the EOS configuration. Thus the configuration hash does not match and the switches will be in different MSTP regions.

Hi Erik,

Have written an post that shows a configuration example of EXOS to EOS MSTP configuration, might help?
