Step 2. Enter IPv6 PIM view. Command ipv6 pim 3. Set the maximum size of each join or prune message. jp-pkt-size size Remarks N/A By default, the maximum size of a join or prune message is 8100 bytes. Enabling IPv6 PIM to work with BFD IPv6 PIM uses hello messages to elect a DR for a shared-media network. The elected DR is the only multicast forwarder on the shared-media network. If the DR fails, a new DR election process will start after the DR is aged out. However, it might take a long period of time before other routers detect the link failures and trigger a new DR election process. To start a new DR election process immediately after the original DR fails, you can enable IPv6 PIM to work with BFD on a shared-media network to detect failures of the links among IPv6 PIM neighbors. You must enable IPv6 PIM to work with BFD on all IPv6 PIM-capable routers on a shared-media network, so that the IPv6 PIM neighbors can fast detect DR failures and start a new DR election process. For more information about BFD, see High Availability Configuration Guide. Before you configure this feature on an interface, be sure to enable IPv6 PIM-DM or IPv6 PIM-SM on the interface. To enable IPv6 PIM to work with BFD: Step 1. Enter system view. 2. Enter interface view. 3. Enable IPv6 PIM to work with BFD. Command system-view interface interface-type interface-number ipv6 pim bfd enable Remarks N/A N/A By default, IPv6 PIM is disabled to work with BFD. Displaying and maintaining IPv6 PIM Execute display commands in any view. Task Command Display BSR information in the IPv6 PIM-SM domain. display ipv6 pim bsr-info Display information about the routes used by IPv6 PIM. display ipv6 pim claimed-route [ ipv6-source-address ] Display C-RP information in the IPv6 PIM-SM domain. display ipv6 pim c-rp [ local ] Display IPv6 PIM information on an interface. display ipv6 pim interface [ interface-type interface-number ] [ verbose ] Display IPv6 PIM neighbor information. display ipv6 pim neighbor [ ipv6-neighbor-address | interface interface-type interface-number | verbose ] * 161
