The value of vRtrIfEgressFilterId associates an ip-filter-id with an egress interface. Filters control the forwarding and dropping of packets based on IP criteria. A value of zero (0) indicates that there is no ip-filter-id associated with this interface. If this entry indicates a service virtual router interface or the special out-of-band management interface, this object is meaningless and is not applied to the interface.
