Static mapping is used when the remote router does not support Inverse ARP. ✘ Frame Relay Inverse ARP requires LMI capability to construct an address to the DLCI mapping table on the router. ✘ Frame Relay Inverse ARP is disabled by default in Cisco IOS Software for all protocols that are enabled on the physical interface. ✘ Inverse ARP does not work when LMI is disabled. ✔ Frame Relay provides forward and backward congestion notification messages. ✔

Multicasting Global addressing Forward-explicit congestion notification (FECN) Virtual circuit status messages. Backward-explicit congestion notification (BECN)

EVC infrastructure is a Layer 3 platform-independent routing architecture that supports IP over Ethernet services. Ethernet flow point (EFP) is configured on the main interface. Feature commands like MQC-based QoS policies can be specified. EVC infrastructure is a Layer 2 platform-independent bridging architecture that supports Ethernet services. Each Ethernet flow point (EFP) matches a predefined VLAN tag-based criteria.

the protocol used to determine the authentication method ✘ the protocol used to identify the data in the Information field ✘ the protocol used to carry the PPP frame ✘ the protocol used to decode the FCS field ✔ the protocol used to detect the number of padding bytes ✔

LCP is used for basic PPP link setup and operation. ✘ LCP is used for PPP CHAP authentication. ✘ LCP is used for PPP over ATM (PPPoA) setup. ✘ LCP is used for PPP over Ethernet (PPPoE) setup. ✔ LCP is used for PPP over Frame Relay (PPPoFR) setup. ✔

A PVC bundle will not come up unless all the precedence, DSCP, and EXP levels are configured in the bundle. A PVC bundle may contain no more than eight PVCs. A PVC bundle may contain no more than sixteen PVCs A PVC can be in only one PVC bundle A PVC bundle cannot perform precedence and DSCP matching at the same time.
