Description of the VPN connection. IKE Properties – Negotiate SA attributes, determine transforms, hashing and more – Generate and refresh keys using DH – Authenticate peer devices using attributes like IP, FQDN, LDAP DN and more – It has two phases IKE v1 (Phase 1 and 2) IKE v2 (Init and Auth) – Main mode & aggressive mode – ISAKMP negotiates SA for IPSEC. Unknown 14:47:00 CCIE IKEv1 Security VPN Unknown In the first part of the new VPN topology, I will be looking at connecting up the lower left-hand side routers, using a mix of static routes and OSPF to get them talking, and then setting up an IPSec VPN between the ASA and DMVPN-Hub2. By creating a Cisco fragmentation payload (ID 132) that is less than 7 bytes, a remote attacker can crash the router. It is also used when using remote access VPN (Legacy Cisco VPN Client) using IKEv1. IKEv1 Main Mode Message 1 contains IKE header, SA payload, Proposal payload, and Transform payload. If this is mismatched (eg PSK vs RSA) the IKE server will also return NO_PROPOSAL_CHOSEN. Furthermore, the ASA only supports Diffie-Hellman group 5 (and not 14), as well as SHA-1 (and not SHA-256) for IKEv1. The outcome of phase II is the IPsec Security Association.
