The vPC peer-gateway capability allows a vPC switch to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This feature enables local forwarding of such packets without the need to cross the vPC peer link. Which statements are true about the vPC peer-gateway？ （）   

A、 The vPC peer-gateway feature is enabled by default.

B、 The vPC peer-gateway feature can be configured globally under the vPC domain submode.

C、 Enabling the peer-gateway feature automatically disables IP redirects on all interface VLANs mapped over a vPC VLAN to avoid generation of IP redirect messages for packets switched through the peer gateway router.

D、 The vPC peer-gateway feature only works with HSRP protocol.

[多选题] Consistency checks and compatibility checks are performed before a Virtual PortChannel （vPC） is created. During a compatibility check， one vPC peer conveys configuration information to the other vPC peer in order to verify that vPC member ports can actually form a PortChannel.     Which statements about a "Virtual PortChannel graceful consistent check" are true？（）

A、 Graceful consistency check is enabled by default.  B、 When graceful consistency check is enabled， only the links on the secondary peer device are suspended.  C、 Graceful consistency check is disabled by default， so to enable this feature， use graceful consistency-check command under VPC domain configuration mode.  D、 When graceful consistency check is enabled， only the inconsistent VLANs on the secondary peer device are suspended.
