WebA router that participates in Bit Index Multipoint Forwarding. A BFR is identified by a unique BFR-prefix in a BIER domain. BFIR: Bit Forwarding Ingress Router. The ingress border router that inserts the BitString into the packet. Each BFIR must have a valid BFR-id assigned. BFER: Bit Forwarding Egress Router. WebThe Bit Index Forwarding Table In MPLS networks a BIER label is allocated for each Bit Index Forwarding Table (BIFT) from the platform specific, downstream label database ([RFC8296]). This label is associated with a particular combination of BIER Sub-Domain (SD), Set Identifier (SI) and BitStringLength (BSL).

Differences Between Routing and Forwarding Tables

WebA forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet.
