Parameters
ip-address: Specifies the IP address of a destination server, in dotted decimal notation.
global: Forwards converted unicast packets to the server on the public network.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the server belongs. The
VPN instance name is a case-sensitive string of 1 to 31 characters.
Usage guidelines
Specify destination servers on an interface that receives UDP broadcast packets.
You can specify a maximum of 20 unicast and multicast addresses for UDP helper to convert broadcast
packets on an interface.
If you do not specify the ip-address argument, the undo udp-helper server command removes all
destination servers on the interface.
If you specify only the IP address, UDP helper forwards converted unicast packets in the VPN bound to
the interface that receives broadcast packets. If the interface is not bound to any VPNs, UDP helper
forwards the unicast packets on the public network.
