Dell S6000 FTOS 9.0(2.0) Configuration Guide for the System - Page 632

www.dell.com | support.dell.com Figure 31-14 shows the convergence settings when fast-convergence is enabled and Figure 31-15 shows settings when fast-convergence is disabled. These displays appear with the show ip ospf command. Figure 31-14. Command Example: show ip ospf process-id (fast-convergence enabled) FTOS(conf-router_ospf-1)#fast-converge 2 FTOS(conf-router_ospf-1)#ex FTOS(conf)#ex FTOS#show ip ospf 1 Routing Process ospf 1 with ID 192.168.67.2 Supports only single TOS (TOS0) routes SPF schedule delay 5 secs, Hold time between two SPFs 10 secs Convergence Level 2 Min LSA origination 0 secs, Min LSA arrival 0 secs Number of area in this router is 0, normal 0 stub 0 nssa 0 FTOS# Fast-converge parameter setting LSA Parameters Figure 31-15.

Some interface parameter values must be consistent across all interfaces to avoid routing errors. For example, you must set the same time interval for the hello packets on all routers in the OSPF network to prevent misconfiguration of OSPF neighbors. Use any or all of the following commands in CONFIGURATION INTERFACE mode to change OSPFv2 parameters on the interfaces: Command Syntax ip ospf cost ip ospf dead-interval seconds Command Mode Usage CONFIG-INTERFACE Change the cost associated with OSPF traffic on the interface. Cost: 1 to 65535 (default depends on the interface speed). CONFIG-INTERFACE Change the time interval the router waits before declaring a neighbor dead. Configure Seconds range: 1 to 65535 (default is 40 seconds). The dead interval must be four times the hello interval. The dead interval must be the same on all routers in the OSPF network. 610 | Open Shortest Path First (OSPFv2)
