Hierarchy Level


Enable this setting to increase the system limit for the number of loopback filter terms that can be configured. When enabled, you can configure up to 768 loopback filter terms for IPv6, and up to 1152 terms for IPv4. The packet forwarding engine (PFE) will restart upon commit for the new system limits to take effect.

Terms that include a reserved multicast destination such as 224.0.0.x/24, and terms with a time-to-live (TTL) such as 0/1, are not directly supported as match condition in filters used with the loopback address (lo0). Instead, to count packets destined to the reserved multicast address of 224.0. 0.6, you would need to create a filter that specifies protocol OSPF as the match term. An example showing such a configuration is provided below.
