ip nhrp map multicast
To configure nonbroadcast multiaccess (NBMA) addresses used as destinations for broadcast or multicast
packets to be sent over a tunnel network, use the ip nhrp map multicastcommand in interface configuration
mode. To remove the destinations, use the no form of this command.
ip nhrp map multicast {ip-nbma-address | ipv6-nbma-address | dynamic}
no ip nhrp map multicast {ip-nbma-address | ipv6-nbma-address | dynamic}
Syntax Description
NBMA address that is directly reachable through the
NBMA network. The address format varies depending
on the medium that you are using.
ip-nbma-address
IPv6 NBMA address.
This argument is not supported in Cisco IOS
XE Denali 16.3.1.
Note
ipv6-nbma-address
Dynamically learns destinations from client
registrations on the hub.
dynamic
Command Default
No NBMA addresses are configured as destinations for broadcast or multicast packets.
Command Modes
Interface configuration (config-if)
Command History
ModificationRelease
This command was introduced.Cisco IOS XE Denali 16.3.1
Usage Guidelines
In Cisco IOS XE Denali 16.3.1, this command supports only IPv4; the ipv6-nbma-address argument
although available on the switch, will not work if configured.
Note
This command applies only to tunnel interfaces. This command is useful for supporting broadcasts over a
tunnel network when the underlying network does not support IP multicast. If the underlying network does
support IP multicast, you should use the tunnel destination command to configure a multicast destination
for transmission of tunnel broadcasts or multicasts.
When multiple NBMA addresses are configured, the system replicates the broadcast packet for each address.
