This chapter explains and shows the RipEX and CISCO ASA configuration steps and IPsec interconnectivity over the Ethernet infrastructure. 187. 2 0. The following options are available in the VPN Creation Wizard after the tunnel is created: So now I figured I’d continue that trend and cover the configuration of an IPSec VPN between 2 Cisco IOS routers. 155. 2. 1. The "IKE Peer" IP address is the remote IP that you are terminating the tunnel to. Verify that something is displayed. xxx. Here are the relevant parts of both configurations. Now, that the IPSec SAs have been established the process is pretty much complete and the IPSec VPN (both phase I and II) is negotiated and formed. This should result in isakmp phase 1 negotiation and phase 2 should build an IPSEC SA relationship between the GRE endpoints. 1. Can anyone help? Simple debugging commands. x LAN-to-LAN (L2L) IPsec VPN configuration, you must specify the <name> of the tunnel group as theRemote peer IP Address(remote tunnel end) in the tunnel-group <name> type ipsec-l2l command for the creation and management of the database of connection-specific records for IPsec. 2. When a Cisco ASA unit has mutiple subnets configured, multiple phase 2's must be created on the FortiGate, and not just multiple subnets. But this doesn’t seem to be working.
