Refer to the exhibit.

What is the consequence of configuring peer-gateway on the two vPC peers N7K-1 and N7K-2?

A. Nothing, this is the standard vPC configuration to make the feature work.

B. The downstream device detects only one of the vPC peers as its gateway.

C. The downstream device can use DMAC of N7K-1 on the link to N7K-2, and N7K-2 forwards the packet.

D. This configuration enables the downstream device to use DHCP to obtain its default gateway.

DRAG DROP
Drag the description on the left to the most appropriate FCoE protocol or feature on the right.

正解：

Explanation:

ENODES: During FLOGI or FDISC, the ENode advertises the addressing modes it supports. If the FC switch supports an addressing mode that the ENode uses, the virtual link can be established, and the devices can communicate.
FIP: FIP is the set of control plane functions that enable discovery of FCoE-capable devices across FCoE passthrough switches and establishment of legal combinations of virtual links.
FCF: FCoE Initialization Protocol (FIP) is the FCoE control protocol responsible for establishing and maintaining Fibre Channel virtual links between pairs of FCoE devices
(ENodes or FCFs). During the virtual link establishment phase, FIP first discovers FCoE
VLANs and remote virtual FC interfaces; then it performs virtual link initialization functions
(fabric login [FLOGI] and fabric discovery [FDISC], or exchange link parameters [ELP]) similar to their native Fibre Channel equivalents. After the virtual link is established, Fibre
Channel payloads can be exchanged on the virtual link, and FIP remains in the background to perform virtual link maintenance functions; it continuously verifies reachability between the two virtual FC interfaces on the Ethernet network, and it offers primitives to delete the virtual link in response to administrative actions to that effect. This document does not describe the virtual link maintenance functions of FIP.
