ExtremeWare XOS 11.5 Command Reference Guide
1815
configure pim crp static
configure pim crp static <ip_address> [none | <policy>] {<priority> [0-
254]}
Description
Configures a rendezvous point and its associated groups statically, for PIM sparse mode operation.
Syntax Description
Default
The default setting for priority is
0
, which indicates highest priority.
Usage Guidelines
In PIM-SM, the router sends a join message to the rendezvous point (RP). The RP is a central multicast
router that is responsible for receiving and distributing multicast packets. If you use a static RP, all
switches in your network must be configured with the same RP address for the same group (range).
The policy file contains a list of multicast group addresses served by this RP.
This policy file is not used for filtering purposes. As used with this command, the policy file is just a
container for a list of addresses. So a typical policy file used for RP configuration will look a little
different from a policy used for other purposes.
If routers have different group to RP mappings, due to misconfiguration of the static RP (or any other
reason), traffic will be disrupted.
Example
The following command statically configures an RP and its associated groups defined in policy file
rp-
list
:
configure pim crp static 10.0.3.1 rp-list
The following is a sample policy file:
entry extreme1 {
if match any { }
then { nlri 224.0.0.0/4 ;
nlri 239.255.0.0/24 ;
nlri 232.0.0.0/8 ;
nlri 238.1.0.0/16 ;
ip_address
Specifies a static CRP address.
none
Deletes the static rendezvous point.
policy
Specifies a policy file name.
priority
Specifies a priority setting. The range is 0 - 254.
