IPSec Proposals offered by Router:
Phase 2: Proposal1: IPSec ESP with DES and HMAC-SHA1
Phase 2: Proposal2: IPSec ESP with AES(256-bit) and HMAC-SHA1 IPSec
Proposal offered by NW2:
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.
