Technology Review
A crypto map entry is a single policy that describes how certain traffic is to be secured. There are two
types of crypto map entries:
ipsec-manual
and
ipsec-ike
. Each entry is given an index, which is used to
sort the ordered list.
When an unsecured packet arrives on an interface, the crypto map set associated with that interface is
processed in order. If a crypto map entry matches the unsecured traffic, the traffic is discarded.
When a packet is to be transmitted on an interface, the crypto map set associated with that interface is
processed in order. The first crypto map entry that matches the packet will be used to secure the packet.
If a suitable SA exists, that is used for transmission. Otherwise, IKE is used to establish an SA with the
peer. If no SA exists, and the crypto map entry is “respond only,” the packet is discarded.
When a secured packet arrives on an interface, its SPI is used to look up an SA. If an SA does not exist,
or if the packet fails any of the security checks (bad authentication, traffic does not match SA selectors,
etc.), it is discarded. If all checks pass, the packet is forwarded normally.
