Here is the output from the router:
r6(config)#source-bridge transparent ?
<1-4095> Source-route ring group attached to the transparent bridge
r6(config)#source-bridge transparent 100 ?
<1-4095> Pseudo-ring number of the transparent bridge
fastswitch Enable/disable fastswitching on sr/tlb bridge
r6(config)#source-bridge transparent 100 10 ?
<1-15> Bridge number to the transparent bridge
r6(config)#source-bridge transparent 100 10 2 ?
<1-255> Transparent bridge group attached to the virtual ring
If we take a look at the show commands I added below you can see that r6
includes bridge-group 1 within its ring-group:
(clipped from r6# show source-bridge)
Ring Group 100:
No TCP peername set, TCP transport disabled
Maximum output TCP queue length, per peer: 100
Rings:
bn: 2 rn: 10 locvrt ma: 400a.cec6.2507 Bridge-group 1 fwd: 104
bn: 10 rn: 6 local ma: 400a.cec6.2587 TokenRing0/0 fwd: 105
And you can also see that r6 includes ring-group 100 within bridge-group 1:
(clipped from r6# show bridge)
Bridge Group 1:
Address Action Interface Age RX count TX count
0000.0c4a.99c6 forward Ethernet0/0 2 113 104
00e0.1ee7.fd92 forward Ethernet0/0 0 18 0
0000.0c09.8f2c forward RingGroup100 2 107 105
And you can also see on the show rif command on r4
r4#sh rif
Codes: * interface, - static, + remote
Dst HW AddrSrc HW Addr How Idle(min) Vlan Routing Information Field
0005.772b.8c82 N/A To0 0 - -
0000.3090.f134 N/A To0 * - -
0000.3052.9963 N/A To0 0 - - 0A10.0041.006A.0642.00A0
MAC address 0000.3052.9963 = r3's ethernet interface IP addressed 34.0.0.3.
r4#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 34.0.0.3 0 0000.3052.9963 SNAP TokenRing0
Internet 34.0.0.4 - 0000.3090.f134 SNAP TokenRing0
Let's read the RIF back most of the numbers I've used are the same in hex as
they are in decimal so it's not too bad (I've copied the RIF above each line
of text to correlate it's ring or bridge number to the RIF):
0A10.0041.006A.0642.00A0
r4 first sends onto local ring 4
0A10.0041.006A.0642.00A0
next the packet hits bridge 1
0A10.0041.006A.0642.00A0
next the packet hits ring 6
0A10.0041.006A.0642.00A0
next the packet hits bridge 10 (Pseudo-ring number of the transparent
bridge)
0A10.0041.006A.0642.00A0
next the packet hits ring number 64 (Hex 64 = Decimal 100 = ring-group)
0A10.0041.006A.0642.00A0
next the packet hits bridge number 2 (Bridge number to the transparent
bridge)
0A10.0041.006A.0642.00A0
and lastly the packet arrives on the destination "ring" 10
