2. If necessary, you can remove a group from the range of groups for an RP
with a deny statement. Use this command:
Syntax: deny [host <A.B.C.D> | <A.B.C.D> <wildcard bits>]
For example, you want Router 1 to be RP for all multicast groups except
for group 239.255.255.1, which will be used in only one section of the
network. You would configure the ACL for Router 1 to exclude the specific
group:
ProCurve(config-std-nacl)# deny host 239.255.255.1
You would then enter a permit statement to allow all multicast addresses
as follows:
ProCurve(config-std-nacl)# permit 224.0.0.0 15.255.255.255
You must enter the deny statement before the statement that permits the
range of groups because the ProCurve Secure Router processes ACL
entries in order and stops as soon as it finds a match. The more general
permit statement allows the address that should be denied.
3. Enter a permit statement for the group address or range or addresses that
the RP will support:
Syntax: permit [host <A.B.C.D> | <A.B.C.D> <wildcard bits>]
Enter an address with wildcard bits to select a range of groups. For
example, you can configure an RP to support half of all possible multicast
groups, those between 232.0.0.0 and 239.255.255.255. A one in the wild-
card bits instructs the router to ignore the associated bit in the address.
Another way of thinking of wildcard bits is that adding the bits to the
specified address gives you the last address in the range. For this example,
you would enter:
ProCurve(config-std-nacl)# permit 232.0.0.0 7.255.255.255
If you are configuring a static RP support a single group, use the host
keyword to specify the address for that one group. For example:
ProCurve(config-std-nacl)# permit host 239.255.255.1
Associating the Static RP with the ACL. Next, you must specify the
address of the RP and associate it with the ACL you have configured for it.
Move to the PIM sparse configuration mode context and enter this command:
Syntax: rp-address <A.B.C.D> access-group <listname>
