Huawei quidway s7700 - Checking the Configuration; Adjusting Control Parameters for Maintaining Neighbors

NOTE
This configuration is optional. By default, the C-RP address carried in the received advertisement message
and the address of the group that the C-RP serves are not checked, and all received advertisement messages
are received and added to the RP-set.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
pim-ipv6
The PIM-IPv6 view is displayed.
Step 3 Run:
crp-policy { advanced-acl6-number | acl6-name acl6-name }
The range of legal C-RP addresses and the range of groups that C-RPs serve are limited. When
a switch receives an advertisement message, the switch checks the C-RP address and the address
of the group that the C-RP serves in the message. The advertisement message is received and
added to the RP-set only when the C-RP address and the group address are in the legal address
range. The C-RP spoofing is thus avoided.
{ advanced-acl6-number | acl6-name acl6-name }: specifies the number of the advanced ACL.
The ACL defines the filtering policy to limit the range of legal C-RP and the range of groups
that the C-RP serves.

13.5.7 Checking the Configuration
After the control parameters of C-RPs and C-BSRs are adjusted, you can check information
about the BSR and RP and check whether a BSR boundary is configured on the interface through
commands.
Procedure
l Run the display pim ipv6 bsr-info command to check information about BSRs in the PIM-
SM domain.
l Run the display pim ipv6 rp-info [ ipv6-group-address ] command to check information
about RPs in the PIM-SM domain.
----End
13.6 Adjusting Control Parameters for Maintaining
Neighbors
Multicast devices establish PIM neighbor relationships and negotiate various control parameters
by exchanging Hello messages. You can adjust the parameters carried in Hello messages as
required. If there is no special requirement, adopt default values.
