Configuring the IPsec Interface¶
TNSR supports routed IPsec via the
ipsecX interface. The number of the
ipsec interface corresponds to the index number of the tunnel set
previously. For example
ipsec tunnel 0 is
ipsec tunnel 2
These IPsec interfaces are used to configure routed IPsec connectivity and they behave like most other interfaces. For example, they can have access lists defined to filter traffic.
tnsr(config)# interface ipsec0 tnsr(config-interface)# ip address 126.96.36.199/30 tnsr(config-interface)# exit
In this example, the
ipsec0 interface is configured with an IP address and
the peer will have its own IP address in the same subnet. This allows the two
endpoints to communicate directly over the IPsec interface and also gives the
peer an address through which traffic for other subnets may be routed. When
configured in this way, it acts like a directly connected point-to-point link
to the peer.
