7.1.2 Route Capacity Limitation
Huge routing tables are usually caused by OSPF route entries and BGP route entries.
Therefore, the route capacity limitation of a switch applies only to OSPF routes and
BGP routes, instead of static routes and RIP routes. The route capacity limitation is
implemented by controlling the size of the free memory of the switch.
When the free memory of the switch is equal to or lower than the lower limit, OSPF or
BGP connection will be disconnected and OSPF or BGP routes will be removed from
the routing table.
z
If automatic protocol connection recovery is enabled, when the free memory of
the switch restores to a value larger than the safety value, the switch
automatically re-establishes the OSPF or BGP connection.
z
If the automatic protocol connection recovery function is disabled, the switch will
not reestablish the disconnected OSPF or BGP connection even when the free
memory restores to a value larger than the safety value.
7.2 Route Capacity Limitation Configuration
Route capacity limitation configuration includes:
z
Configuring the lower limit and the safety value of switch memory,
z
Enabling/disabling the switch to recover the disconnected routing protocol
automatically.
