I have a linux box that is terminating 14 L-to-L VPNs. I am migration this box to Cisco 6500 with SPA-IPSEC module. I have just one WAN router.
I want to put the 6500/IPSEC parallel to the Linux box to migrate one site at a time. How can I do that?
The big question is that the Linux box and the WAN router are connected to the 6500 via a VLAN. So their ports are configured as access ports.
Can I route one site packets from the WAN router to the IPSEC module and still have L2 connectivity to me Linux box?
If I configure the WAN router access port at 6500 to be crypto connected to a port VLAN do I lose L2 connectivity to the Linux?
