VPLS SAP Ingress IP Filter Override
When an IP Interface is attached to a VPLS service context, the VPLS SAP provisioned IP filter
for ingress routed packets may be optionally overridden in order to provide special ingress
filtering for routed packets. This allows different filtering for routed packets and non-routed
packets. The filter override is defined on the IP interface bound to the VPLS service name. A
separate override filter may be specified for IPv4 packet types.
If a filter for a given packet type (IPv4) is not overridden, the SAP specified filter is applied to the
packet (if defined).
The following tables lists ACL Lookup behavior with and without Ingress Override filter attached
to an IES interface in a R-VPLS service:
