DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide The fields that can be configured are described below: Parameter Interface Name Hash Mask Length Priority Description Enter the VLAN interface name used here. Enter the hash mask length for RP selection here. The range is from 0 to 128. The mask (128 bits maximum) that is to be logically AND with the group address before the hash function is executed. All groups with the same seed hash (correspond) to the same RP. Therefore, one RP can be derived for multiple groups. By default, this value is 126. Select the Default option to use the default value. Enter the priority value for the BSR candidate here. The range is from 0 to 255. The BSR with the larger priority is preferred. If the priority values are the same, the router with the larger IPv6 address is the BSR. By default, this value is 64. Select the Default option to use the default value. 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. PIM for IPv6 BSR Table This window is used to view IPv6 PIM BSR information. To view the following window, click L3 Features > IP Multicast Routing Protocol > PIM > PIM for IPv6 > PIM for IPv6 BSR Table, as shown below: Figure 6-125 PIM for IPv6 BSR Table Window 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.
