Information About ASA 5505 Interfaces
With the Base license in routed mode, the third VLAN can only be configured to initiate traffic to one
other VLAN. See Figure 1-1 for an example network where the Home VLAN can communicate with the
Internet, but cannot initiate contact with Business.
Figure 1-1 ASA 5505 with Base License
With the Security Plus license, you can configure 20 VLAN interfaces in routed mode, including a
VLAN interface for failover and a VLAN interface as a backup link to your ISP. You can configure the
backup interface to not pass through traffic unless the route through the primary interface fails. You can
configure trunk ports to accommodate multiple VLANs per port.
Note The ASA 5505 supports Active/Standby failover, but not Stateful Failover.
See Figure 1-2 for an example network.
