Antispoofing with dynamic routing

[cem82]

Hi

For antispoofing config (on R80.30 and R81.10), is it fine to be internal > defined by routes on the OSPF/BGP interfaces?  Do routing changes take effect immediately in terms of the antispoofing checks or does it recalculate every X amount of time etc?  Any gotcha that we should be aware of?

Thanks
