Enabling Evi Flooding For All Destination-Unknown Frames; Enabling Selective Flooding For A Mac Address; Displaying And Maintaining Evi - H3C S7500X Series Configuration Manual

Enabling EVI flooding for all destination-unknown
frames
By default, the device floods unknown unicast and multicast frames only to internal interfaces. EVI
flooding enables the device to flood all destination-unknown frames to an EVI tunnel interface.
To enable EVI flooding for all destination-unknown frames:
Step
1. Enter system view.
2. Enter EVI tunnel interface
view.
3. Enable EVI flooding.

Enabling selective flooding for a MAC address

CAUTION:
Do not configure selective flooding for local unicast MAC addresses. The setting might cause
remote devices to drop packets destined for the MAC address.
By default, the device floods unknown unicast and multicast frames only to internal interfaces.
If an application uses a special multicast address that requires flooding across sites and cannot be
added to a multicast forwarding table by IGMP snooping, enable selective flooding for the multicast
address.
To enable selective flooding for a MAC address:
Step
1. Enter system view.
2. Enter EVI tunnel interface
view.
3. Enable selective flooding for
the MAC address in a set of
VLANs.

Displaying and maintaining EVI

information.
