IPv6 PIM view
acl6-number: Basic IPv6 ACL number, in the range of 2000 to 2999. When an IPv6
ACL is defined, the source keyword in the rule command specifies a legal BSR
source IPv6 address range.
Use the command to configure a legal BSR address range to guard
bsr-policy
against BSR spoofing.
Use the
undo bsr-policy
range.
By default, there are no restrictions on the BSR address range, namely all the
received BSR messages are regarded to be valid.
# Configure a legal BSR address range so that only routers on the segment
2001::2/64 can become the BSR.
