Route Scaling

The following table provides information on IPv4 and IPv6 route scaling. The route table is a shared hardware resource where IPv4 routes consume one entry and IPv6 routes with a prefix length less than 64 consume two entries.

The route scaling does not depend on the protocol itself, but rather the general system limitation in the following configuration modes:

The total number of routes include local routes.

The stated numbers in the preceding rows are one-dimensional where the given number implies that only routes for that address family or type are present. For a given row in the table, the maximum scaling number is ‘x‘ IPv4 routes OR ‘y‘ ipv6 <= 64 routes (not a combination of both).
