Re: Routing between 2 tokenring vlans using RSM

Patrick,

depending on what you're trying to achieve routing, depending on whether
you'll have to srb or not.

The deadset simplist way is to set your trcrf to use srt bridging mode,
and the trbrf to use ieee spanning tree. Then just create the vlans, and
add IP addresses. No need for any srb-related configs.

If for srb as well as routing, then there are a few parts you'll have to
fix up. The trcrf vlans numbers are hex. So:

  hex decimal
  0x11 -> 17
  0x12 -> 18
  0x22 -> 34
  0x23 -> 35

Then fix up your vlan 11's mtu size.

Next, you'll need for each trbrf, a trcrf connecting to a virtual ring
(you've got the idea in the RSM):

 - change trcrf 12's ring number to 0x64 (100 decimal)

    set vlan 12 ring 64 (defaults to hex entry)
    set vlan 23 ring 64

that just about does it.. :^)

Did the config in the RSM generate the mtu statement, or you added that
in? Haven't played with it for a while now, so would like to know.

Regards

Bernard.
