Setting the Range of Valid C-RP Addresses

Procedure

1. Run system-view

   The system view is displayed.

2. Run acl ipv6 { name advance-acl6-name [ advance | [ advance ] number advance-acl6-number ] | [ number ] advance-acl6-number } [ match-order { config | auto } ]

   An advanced ACL6 is created, and the advanced ACL6 view is displayed.

3. Run rule [ rule-id ] [ name rule-name ] { deny | permit } ipv6 [ destination { destination-ipv6-address prefix-length | destination-ipv6-address/prefix-length | any } | source { source-ipv6-address prefix-length | source-ipv6-address/prefix-length | any } ] ^*

   Rules are configured for the advanced ACL6.

   Run the rule command, set the source parameter to a valid C-RP source address range, and set the destination parameter to a multicast group address range to be served by C-RPs.

4. Run quit

   Return to the system view.

5. Run pim-ipv6

   The IPv6 PIM view is displayed.

6. Run crp-policy { advanced-acl6-number | acl6-name acl6-name }

   The range of valid C-RP addresses and the range of IPv6 multicast groups that a C-RP serves are set.

   • If the C-RP address or the address of a multicast group that a C-RP serves contained in an Advertisement message is not within the range defined by an IPv6 ACL or no action is defined in the IPv6 ACL for processing such an Advertisement message, the BSR discards the Advertisement message and does not add the C-RP information carried by the Advertisement message to the RP-Set.

   • If only advanced-acl6-number or acl6-name acl6-name is set but no IPv6 ACL is set, the BSR denies all Advertisement messages.

   

   • If an Advertisement message from a C-RP matches an ACL rule and the action is permit, the BSR permits this message.
   • If an Advertisement message from a C-RP matches an ACL rule and the action is deny, the BSR denies this message.
   • If an Advertisement message from a C-RP does not match any ACL rule, the BSR denies this message.
   • If a specified ACL does not exist or does not contain rules, the BSR denies all messages from any C-RP.

7. Run commit

   The configuration is committed.
