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.
Examples
# Specify the destination server 192.1.1.2 for UDP helper on VLAN-interface 100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] udp-helper server 192.1.1.2
# Specify the destination server 192.1.1.2 on the public network for UDP helper on VLAN-interface
100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] udp-helper server 192.1.1.2 global
