Routercommand,Routerconfiguration:Matrix‐>Router(config‐router)#
Usage
SettingdatabaseoverflowallowsyoutosetalimitonthenumberofexternalLSAs.Ifthelimitis
exceeded,self‐originatedexternalLSAswillberemovedsothatOSPFcanhandlethelarge
numberofexternalLSAscomingfromanotherrouter.Whenthewarninglevelisset,aSyslog
message
willbeissuedwhenthenumberofexternalLSAshasreachedthespecifiedlevel.Every
exit‐overflowintervalseconds,thedatabasewillbecheckedand,ifthetotalislessthanthelimit
specified,theselforiginatedexternalLSAswillberestored.
The“no”formofthiscommandremovesthedatabase
overflowlimits.
