Operation Manual – Routing ProtocolH3C S5600 Series Ethernet Switches Chapter 7 Route Capacity Configuration7-27.1.2 Route Capacity LimitationHuge 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 andBGP routes, instead of static routes and RIP routes. The route capacity limitation isimplemented 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 orBGP connection will be disconnected and OSPF or BGP routes will be removed fromthe routing table.z If automatic protocol connection recovery is enabled, when the free memory ofthe switch restores to a value larger than the safety value, the switchautomatically re-establishes the OSPF or BGP connection.z If the automatic protocol connection recovery function is disabled, the switch willnot reestablish the disconnected OSPF or BGP connection even when the freememory restores to a value larger than the safety value.7.2 Route Capacity Limitation ConfigurationRoute 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 protocolautomatically.7.2.1 Configuring the Lower Limit and the Safety Value of the SwitchMemoryFollow these steps to set the lower limit and the safety value of switch memory:To do...
