Using the undo dampening command,you can cancel the configured route attenuation.If no parameters are configured in this command, then BGP route dampening is valid,and the parameters take default values. The parameters are mutually dependent.Once any parameter is configured, all other parameters should also be specified.For related commands, see reset dampening, reset bgp flap-information, displaybgp routing-table dampened, display bgp routing-table flap-information.Example# Configure the parameters of BGP routing dampening.[3Com-bgp] dampening 15 15 1000 2000 100004.1.8 debugging bgpSyntaxdebugging bgp { all | event | { keepalive | open | packet | update } [ receive |send ] [ verbose ] } }undo debugging bgp { all | event | keepalive | open | packet | update }ViewAll viewsParameterall: Enable all kinds of bgp debugging switch.74
