Joining Two Networks using Multiple IPSec
Proposals Example
The following example demonstrates how a security gateway can use multiple
IPSec(phase2) proposals to form an IP security tunnel to join two private
networks: 10.0.1.0/24 and 10.0.2.0/24.
IKE Proposal offered by both Router and NW2:
y
Phase 1: 3DES and SHA1
IPSec Proposals offered by Router:
y
Phase 2: Proposal1: IPSec ESP with DES and HMAC-SHA1
y
Phase 2: Proposal2: IPSec ESP with AES(256-bit) and HMAC-SHA1 IPSec
Proposal offered by NW2:
y
Phase 2: Proposal1: IPSec ESP with AES(256-bit) and HMAC-SHA1
In this example, the Router router offers two IPSec proposals to the peer while
the NW2 router offers only one proposal. As a result of quick mode
negotiation, the two routers are expected to converge on a mutually acceptable
proposal, which is the proposal ‘IPSec ESP with AES(256-bit) and HMAC-
SHA1’ in this example.
