My company is in the process of converting our IP address to a different class C and would like to change our host IPSEC tunnel end point to something different ...THis has to be a slow cut over so I can i use this config for my interface and use the secondary as my IPSEC source.
ip address 208.74.x.x 255.255.255.128 secondary
ip address 67.132.x.x 255.255.255.224
no ip proxy-arp
no cdp enable
