Parameters

mac-address: Specifies a MAC address, which cannot be all Fs.

vlan vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each VLAN item specifies a VLAN ID or a range of VLAN IDs in the form of start-vlan-id to end-vlan-id, where the end VLAN ID must be greater than the start VLAN ID. Valid VLAN IDs are from 1 to 4094.

Usage guidelines

	CAUTION: Do not configure selective flooding for a unicast MAC address that might be learned at an edge device's data plane. The configuration can cause packets destined for the MAC address to be dropped on remote devices after they obtain the MAC address entry through EVI IS-IS.

By default, the device floods unknown unicast and multicast frames only to internal interfaces.

The device floods a destination unknown frame to an EVI tunnel interface if the frame's destination MAC address and VLAN ID match a selective flooding entry.

Enable selective flooding for special multicast addresses that require flooding across sites but cannot be added to a multicast forwarding table by IGMP snooping.

Examples

# Configure selective flooding for 000f-e201-0101 in VLANs 1 to 10 on the EVI tunnel interface Tunnel 101.
