DLSW Questions

I don't have token ring (only ethernet) in my lab network so I cannot test
this. Can someone tell me if this configuration answers the questions
below?

The layout looks like: R2 tokenring, R4 tokenring, and R5 ethernet. Here is
a question from one of my practice labs.

Scenario: Configure R2, R4, and R5 for DLSW. Configure filter so that the
only protocol that is transported via dlsw is netbios and apply this filter
to R2 remote peer statements. Ensure that R4 inform all his peers that R4
can only reach mac 4444.4444.4444.

Here is what I think my configuration would look like:

R5:
  dlsw local-peer peer-id 150.100.5.5 group 100 promiscuous
  dlsw remote-peer 0 tcp 150.100.2.2
  dlsw bridge-group 1
  int loopback 0
    ip address 150.100.5.5 255.255.255.0
  int e0
    bridge-group 1
  bridge 1 protocol ieee

R2:
  source-bridge ring-group 200
  dlsw local-peer peer-id 150.100.2.2 group 100 border promiscuous
  dlsw remote-peer 0 tcp 150.100.4.4 lsap-output-list 200
  dlsw remote-peer 0 tcp 150.100.5.5 lsap-output-list 200
  int loopback 0
    ip address 150.100.2.2 255.255.255.0
  int token0
    source-bridge 25 1 200
    source-bridge spanning
  access-list 200 permit 0xF0F0 0x0101

R4:
  source-bridge ring-group 400
  dlsw local-peer peer-id 150.100.4.4 group 100 promiscuous
  dlsw remote-peer 0 tcp 150.100.2.2
  dlsw icanreach mac-exclusive
  dlsw icanreach mac-address 4444.4444.4444 mask ffff.ffff.ffff
  int loopback 0
    ip address 150.100.4.4 255.255.255.0
  int token0
    source-bridge 25 1 400
    source-bridge spanning

Questions:
1. Is this a correct configuration? Can someone try this out and let me
know or give me a sample configuration that does work and accomplishes these
tasks?
2. If I do "show dlsw peer" on r2, I see 2 connected peers (R5 & R4).
However, if I use same command on R4 or R5, I only see 1 connected peer. Is
it because when you use border peers, the connections are dynamic
(connections brought up only when needed) ? On lab exam, should I not use
border peers hub/spoke and just type out all remote peers?
3. If I do "show dlsw capabilities" on R2, I see that reachable mac address
as correct. Is this the only way I can verify that my configuration is
working as I have no actual hosts to test with?

thanks
