I have researched to the max this past weekend, and I am sure that what I need to do is a 'bridge irb', but when I tried it the first time it did not work. When I tried to set the ip address of the bvi1 interface to be on the same subnet as both offices, Cisco won't let me do that. It says the...

I have made a drawing of my Topology here: http://www.sanjuantitle.com/BridgeScenario1.pdf No matter what I have tried, the line protocol for the Serial interface will not stay up. I have tried setting it up as a 'routed' path, changing the subnet at the Branch office and configuring ip...

Oh, yeah, one more thing.... I may be able to set up the Serial interfaces as "asynchronous" using ppp encapsulation. Would that be any better than just going back to a "bridged" configuration? Again, THANKS!

A couple of weeks ago I started a thread here: thread557-1277212 I have learned SO MUCH over the last two weeks, including the exact nature of the equipment that our Telcomm guys are using to provide the physical line from our Main office to our Satellite. We initially discussed bridging, but...

HELP one more time, please! I got the router, and the PCs at the Satellite office to ping to the isp dsl router, that means I'm getting out onto the internet. However, I only discovered today that there is no DNS name resolution taking place at the satellite. I have a private DNS server for...

Tim, Thank you, thank you, thank you! That works like a charm! I was aware that I didn't know too much about the RIP statements, I just thought "the more the merrier", I guess. Anyway, it sounds like you could answer a couple more quick questions for me.... 1. If I take the 'version 2'...

The satellite does need ONLY outbound internet, and I do have NAT enabled on Main router. See my original post: An interesting thing happens when I run a traceroute from a PC at the satellite office to 10.1.1.13 (DSL Router "Internet") the route shows: 1. 192.168.41.201 (FastEth0 on Satellite...

Ooops, my last posting has an error. The last question should be: How would I tell the DSL device how to get back to the 192.169.41.0 network by using commands on either the MAin Cisco router or the Satellite Cisco router? Thanks!

Yes the device at 10.1.1.13 is the Ethernet connection to the DSL router that was provided by our ISP. I cannot access that router configuration. I am assuming that this device "knows how" to get back to the 192.168.40.0 network because it is directly connected to the same router? How would...

I did this first. No. Can you give me an idea of how to do that? I tried the following line in the Main Router: ip route 10.1.1.0 255.255.255.0 192.169.0.1 (Of course, I used the actual network address and mask for the ISP DSL Router) That didn't appear to work, so I probably did that wrong...

I have a main office, and we are adding a satellite office, and I am trying to share the DSL Internet located at the main office with both sites. Here is a drawing of my current topology: http://www.sanjuantitle.com/RobsNetTopology.tif On both Cisco routers I have the following protocol...

Very nice catch, I hadn't thought of that. I added the "permit" line to the access-list, and then restarted both routers. It still does not ping from satellite subnet to dsl ip. Should my global 'ip route' command in the satellite router point to the Eth0 interface at the Main office, or to...

The 'cloud' between the main and satellite offices is a "fractional T1" line, with some channels being used for the phone system and others used for data. Changing the Subnet at the satellite to 192.168.41.0/24 did the trick as far as routing from one site to the other. I am now able to make...

OK, guys, I am unable to get the "transparent bridge" connection to work. I am attempting now to route traffic across this connection and I totally need help. Situation: Main Office is on ip network 192.168.40.0 Router type is Cisco 1721 with WIC T1 serial card and WIC ETH1 Ethernet card...

I am still having problems with this transparent bridge, and I wonder if anyone can shed any light on this. I have the physical serial connection done, both routers show that the interface Serial0 is up, and the line protcol is up. However, network traffic is still not flowing across this...

Thanks for the reply, Andy. The only reason why I'm bridging instead of routing is because the telcomm people told me they have set up this type of "seamless" or "transparent" connection before, and the users at the satellite office will see no difference than when they are here in our office...

I am trying to follow the instructions of our telcomm people in setting up a "transparent bridge" between our main office and our new satellite office. I have a Cisco 1721 at each location, both have WIC 1T Serial Interface cards, plus the FastEthernet LAN ports. If I understand this...
