IP RIP Filter Precedence
Whenever you use multiple “allow” filters you must first define a filter to block all RIPs. Then,
any other “allow” filters of the same type must be
at least as specific in all areas in order for
the filters to work. Note that filtering precedence is related only to “allow” filters. Multiple
“block” filters can be defined with varying specificity in each of the areas of the filter. The
filtering done by the configurable parameters (Address/Mask) in the “allow” filter must be at
least as specific as the filtering defined in the “block” filter.
