Configuring Site-to-Site VPN in Multi-Context Mode
Follow these steps to allow site-to-site support in multi-mode for all platforms except the 5505. By
performing these steps, you can see how resource allocation breaks down.
Step 1 To configure the VPN in multi-mode, configure a resource class and choose VPN licenses as part of the
allowed resource. The “Configuring a Class for Resource Management” section on page 1-17 provides
these configuration steps. The following is an example configuration:
class ctx1
limit-resource VPN Burst Other 100
limit-resource VPN Other 1000
Step 2 Configure a context and make it a member of the configured class that allows VPN licenses. The
“Configuring a Security Context” section on page 1-20 provides these configuration steps. The
following is an example configuration:
context context1
member ctx1
allocate-interface GigabitEthernet3/0.2
allocate-interface GigabitEthernet3/1.2
allocate-interface Management0/0
