DGS-1520 Series Gigabit Ethernet Smart Managed Switch Web UI Reference Guide The fields that can be configured are described below: Parameter (S,G) Keepalive Time Description Enter the (S,G) keep-alive time value here. This specifies the period during which the PIM router will maintain the (S, G) state in the absence of explicit (S, G) local membership or (S, G) join messages received to maintain it. The range is from 120 to 65535 seconds. By default, this value is 210 seconds. Select the Default option to use the default value. Click the Apply button to accept the changes made. PIM for IPv6 Multicast Route Table This window is used to display all entries in the IPv6 multicast routing table. The Switch populates the multicast routing table by creating source, group (S,G) entries from star, group (*,G) entries. The star (*) refers to all source addresses, the "S" refers to a single source address, and the "G" is the destination multicast group address. In creating (S,G) entries, the software uses the best path to that destination group found in the unicast routing table, through Reverse Path Forwarding (RPF). To view the following window, click L3 Features > IP Multicast Routing Protocol > PIM > PIM for IPv6 > PIM for IPv6 Multicast Route Table, as shown below: Figure 6-118 PIM for IPv6 Multicast Route Table Window Click the Show Detail button to view detailed information for the specified entry.
