Guidelines for Static and Default Routes

Firewall Mode and Bridge Groups

• In transparent mode, static routes must use the bridge group member interface as the gateway; you cannot specify the BVI.

• In routed mode, you must specify the BVI as the gateway; you cannot specify the member interface.

• Static route tracking is not supported for bridge group member interfaces or on the BVI.

Supported Network Address

• Static route tracking is not supported for IPv6.

• ASA does not support CLASS E routing. Hence, CLASS E network is not routable as static routes.

Clustering and Multiple Context Mode

• In clustering, static route tracking is only supported on the primary unit.

• Static route tracking is not supported in multiple context mode.

Network Object Group

You cannot use a range of network objects or a network object group having a range of IP addresses while configuring a static route.

ASP and RIB Route Entries

All routes and its distance installed on the device are captured in the ASP routing table. This is common for all static and dynamic routing protocols. Only the best distance route is captured in the RIB table.
