what does SR/TLB really do ? [7:54302]

It doesn't look like the Ethernet and Token Ring networks are really bridged?? If they are bridged, then they don't need IP addresses, or they should have IP addresses in the same subnet. The PCs should be in that same subnet also. To make sure you really have created one big bridged/switched network, put everything in the same IP subnet and do some pinging. To test Windows and SR/TLB networking, however, you don't actually need or want IP. Instead, make sure the PCs are using NetBEUI. The bridge should forward their broadcasts and they should find each other. The PCs should not use NetBIOS over IP or IPX. You don't need or want network-layer packet forwarding for your test, if I understand what you are trying to accomplish. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > Barbados#sho cdp neighbors > Capability Codes: R - Router, T - Trans Bridge, B - Source > Route Bridge > S - Switch, H - Host, I - IGMP, r - Repeater > > Device IDLocal Intrfce HoldtmeCapability > Platform Port ID > 000577:25E400 (HSTRA Catalyst 3920) > Tok 0/0172 B S > CAT3920 1/2 > Gozo Eth 0/0156 T S > 1900 7 > 2522_Ser 0/1172 R > 2522 Ser 1 > Barbados# > > The PC's could ping each other even before I enabled EIGRP --- > they are > directly connected. > I wanted to set up SR/TLB so I entered some commands as you can > see in the > log at the bottom of this post > Even after setting up SR/TLB the PC's cannot see each other in > network > neighborhood, so in what way are they connected ? > > http://www.cisco.com/warp/public/701/45.html#5 > > from above link: "If you need to connect stations between > Ethernet and > Token Ring which are local to the router, you must use SR/TLB " > > > sho run > Building configuration... > > Current configuration : 2151 bytes > ! > !

Re: what does SR/TLB really do ? [7:54302]
Thanks for your suggestions. I will try them this afternoon. Cisco's own example for this shows IP address on the interfaces (not the same one's I used) so I put them on. I was also hoping to route the traffic accross the WAN in addition to bridging between PC's but I will get to that after I figure out the first issue !
