I am re-designing my current network and am pretty much replacing all of our LAN gear. I will have dual 6509?s at the core, and pushing a mix of 4507?s and 6509?s to my access layer. I also want to move my servers off of the core and put them on th...

I currently have a PIX 515E connected to my internal LAN on the Inside interface. The inside interface connects to a 2950 switch that acts as the "core". I am replacing the 2950 with a 4507 and am having problems with the clients on the 4507 connec...

My problem is similar to others as far as I can successfully make a vpn connection to my PIX firewall. Once connected, I can not access any network resources. The differnece is that I am going through a CISCO 2514 router. This is a test lab that I...

I have been receiving the PIX syslog 106016 messages over the past week. I have recieved over 50 so far today. Like others, the source address is 127.0.0.1 and destination is one of our public IP address (at random). When sniffing the traffic, the...

Maybe I didn't explain it correctly. It should be L3 to the access unless I totally missed the boat.Let me explain it with using one of our sister companies as an example. All ports are configured as access ports with no vlan assignments (VLAN 1). ...

Ok, thanks. After reading one of the pdf's in the link you sent, I found where it explained this.My last question is, what is the downside to just using two of the addresses in the access layer instead of using a /30. If core 1 interface ip is 17.1...

This is a dumb question, but after going back through this, I'm confused on how the access network will route to the core. Is simply assigning a loopback address on each switch and then adding the loopback to EIGRP enough to tell the access switches...

Great, thanks. That is good info.Now that I think about it, we are doing the SVI config today. We just never use both paths since one router has 8 T1's in a MLPP bundle while the other has a full DS3. Our end design is to go into dual carrier MPLS ...
