Nokia 7210 Configuration Manual page 566

System Management
This command provides the flexibility to earmark resources based on the number of directly
connected interfaces required on the node, allowing the user to decrease the number of
resources for directly connected subnets and consequently increase the number of entries
available for IP routes received from peers. See the description of the
command for detailed information about IP route allocation.
Note:
Default no max-ip-subnets (Software allocates a fixed number of entries towards this to maintain
backward compatibility with releases prior to release 7.0.R3).
Parameters number — Specifies the number of IP subnets for directly connected IP interfaces.
Table 63
566
• Each IPv4 subnet configured on the node requires 1 entry and each IPv6 subnet
configured on the node requires 2 entries. Each IPv6 /64-bit address prefix requires
twice the amount of space needed for an IPv4 address prefix. Additionally, the user
must account for resources required for IPv6 primary and secondary addresses
assigned to an IPv6 interface.
• The number of entries available for IP routes received from a peer is equal to the total
number of L3 forwarding entries supported for the platform subtracted by the number
of entries specified by this command.
• The software allocates entries from this pool on a FCFS (first come first serve) model
based on the order of configuration of IP interfaces. An error is generated when the
maximum limit is reached.
Values Table 63
The minimum number of IPv6 interfaces is 2.
