To configure routing protocols:
1. In the 'Routing' screen, configure the desired routing protocols:
•
Internet Group Management Protocol (IGMP) section:
a. Select the 'Enabled' check box to enable support for IGMP multicasting.
b. Select the 'Enable IGMP Fast Leave' check box if you want MP-20x to stop
forwarding traffic to a host that is the only subscriber, immediately upon
request (without query delay).
c. Select the 'IGMP Multicast to Unicast' check box to enable MP-20x to
convert the incoming multicast data stream into unicast format to route it to
the specific LAN host that had requested the data. In this way, MP-20x
prevents flooding the rest of the LAN hosts with irrelevant multicast traffic.
•
Domain Routing: Select the 'Enabled' check box if you want MP-20x's DNS
server to add a routing entry for the IP address of the reply through the device
from which it arrived, when it receives a reply from an external DNS server. This
means that future packets from this IP address will be routed through the device
from which the reply arrived.
2. Click OK .
