DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide PIM for IPv6 RP Address This window is used to display and configure the IPv6 PIM RP address settings. This feature only affects PIM-SM operation. Use this feature to statically define the RP address for multicast groups that are to operate in sparse mode. Use a single RP for more than one group. The conditions specified by the access list determine for which groups the RP can be used. Multiple RP can be defined, each with a single access list. The new setting overrides the old one. All routers in a domain should have a consistent multicast group to RP mapping. The first hop router that initiates a register message will use the mapping entries to determine the RP for sending the PIM register message destined for a specific group. The last hop router that initiates a join message uses the mapping entries to determine the RP for sending the join and prune message for a specific group. When a router receives a join message, it will check the mapping entries for forwarding of the message. When a RP receives a register message, if the router is not the right RP for the multicast group, a register-stop message will be sent. If the PIM domain is using embedded-RP, only the RP needs to be statically configured as the RP for the embedded RP ranges. The other routers will discover the RP address from the IPv6 group address. If these routers want to select a static RP instead of the embedded RP, the specific embedded RP group range must be configured in the access list of the static RP. To view the following window, click L3 Features > IP Multicast Routing Protocol > PIM > PIM for IPv6 > PIM for IPv6 RP Address, as shown below: Figure 6-134 PIM for IPv6 RP Address Window The fields that can be configured are described below: Parameter RP Address Group Access List Name Override Description Enter the RP IPv6 address here. Enter the standard IPv6 access list that will be used here. Alternatively, click the Show List button to find and select any of the exiting access lists configured on this Switch to be used in this configuration. Select the All Groups option to map the RP to all multicast groups. Selecting this option specifies that the static RP will override dynamically learned RPs. Click the Add button to add a new entry based on the information entered. Click the Delete button to delete an entry based on the information entered. Enter a page number and click the Go button to navigate to a specific page when multiple pages exist. After clicking the Show List button, the following page will appear. 310
