I have recently made a WAN change from T1 to fiber and my Cisco 2600 series router no longer needs to connect over the Serial T1 card. The Serial connection also provided a few voice channels for the old phone system that are no longer needed. I need to keep Main Cisco 2600 router in place because I have many network devices that use it as the gateway instead of my firewall. I will not require the second subnet for Offsite Cisco 2600 anymore either. Please help me with the commands that will be required to remove all instances of the Serial connection and Offsite Cisco 2600. I have included the config of the Main Cisco 2600 below.
Main Cisco 2600 - LAN Interface - 192.168.47.10 (keeping)
Cisco Firewall - 192.168.47.100 (will remain)
Offsite Cisco 2600 - LAN Interface - 192.168.20.10 (no longer needed)
