Just switched over to a 100mb Ethernet circuit from a DS3 and having some issues, routing issues I believe. I'm attaching a drawing to help paint the picture which I'll explain below: DS3 setup DS3 circuit connected to a serial card on Cisco 7206 router, has a /30 network internal to Telco assigned to it FastEthernet port coming off that router with public IP and subnet(was half of class C /25) assigned to it connected to a 'dummy' 12 port switch(basically acting as a hub) The 'dummy' switch has 2 Cisco ASA's connected to it, each with a /26 subnet IP from the public block that we had Also there are 2 Routers connected to this same switch, their IPs are /25 subnet IPs, but they fall outside of the /26 subnet mentioned above for the ASA's. Hope this is not confusing so far... Only had one routing statement on the 7206, ip route 0.0.0.0 0.0.0.0 serial1/0 and everything worked as it should, i was able to ping the 7206 IP from any internal device(either of the ASA's, the 2 routers, etc.) New setup - 100mb Ethernet connection Circuit connected to FastEthernet port that was empty on Cisco 7206 router, has a /30 network internal to Telco assigned to it - c.c.c.90 Same FastEthernet port as was used for original setup now has a new public IP and subnet(went down to /27) assigned to it connected to a 'dummy' 12 port switch(basically acting as a hub) The 'dummy' switch has 2 Cisco ASA's connected to it, each now with a /28 subnet IP from the public block The 2 Routers connected to this same switch, their new IPs are /27 subnet IPs, but they fall outside of the /28 subnet mentioned above for the ASA's. Per Telco had to change the routing statement to point to an IP instead of an interface, so new statement is Ip route 0.0.0.0 0.0.0.0 c.c.c.89                   The Problem: I can not ping the 7206 from either of the 2 routers or the 2 ASA's I can ping the 7206 from my internal network behind the 2 ASA's just fine I can ping the 2 routers and the ASA's from 7206 just fine also HELP ...

Hello everyone, First post here, so please excuse any n00b mistakes... I have a 4507(WS-C4507R) as my core switch running ver. 12.1(19r)EW, multiple VLANs and ports configured in different modes, etc. I'm replacing this switch with another 4507(WS-C4507R+E) running ver. 15.0(1r)SG3. I need to copy as much configuration to the new swich as possible, VLAN(VTP) info mainly as the ports and what plugs into them will be completely rewired/remapped.  I'm wondering if there's a best practices document or if someone has had to do the same and has a proven/working way of doing this. Some items to keep in mind: I would like the new switch to have the same IP and be able to route everything as the current one does as everything uses the current switch as the gateway and it is the Core Switch.  Copying running-config from one to another is the simple part, but that doesn't copy some of the port/interface mode configuration which is vital. My concerns are mostly being able to configure ports the same way on the new switch, i.e. couple of ports have routers hooked up to them, need to be able to copy all the config that's needed to change those ports to the proper mode, etc. Not sure if there's some command that I don't know of to be able to gather that data. Please let me know if you can help. Thanks, N ... View more
