Static multicast routes
The following table describes the parameters of the show ip pim
TABLE 17 Display of show ip pim
This field...Displays...
Number of Anycast RP: The Number of Anycast RP specifies the number of Anycast RP sets in the multicast
| domain. |
|
|
Anycast RP: | The Anycast RP address specifies a shared RP address used among multiple PIM |
| routers. |
|
|
ACL ID: | The ACL ID specifies the ACL ID assigned. |
|
|
ACL Name | The ACL Name specifies the name of the Anycast RP set. |
|
|
ACL Filter | The ACL Filter specifies the ACL filter state SET or UNSET. |
|
|
Peer List | The Peer List specifies host addresses that are permitted in the Anycast RP set. |
|
|
NOTE
MSDP and Anycast RP do not interoperate. If transitioning from MSDP to Anycast RP or vice versa, all RPs in the network must be configured for the same method of RP peering; either Anycast RP or MSDP.
Static multicast routes
Configure static multicast routes to control the network paths, administrative distance, and precedence for multicast routes.
Static multicast routes allow you to control the network path used by multicast traffic. Static multicast routes are especially useful when the unicast and multicast topologies of a network are different. By configuring static multicast routes you don't have to make the topologies similar.
NOTE
In IP multicasting, source IP addresses are unicast addresses while destination IP addresses are multicast (group) addresses. Therefore, in IP multicasting, a route lookup is done for source IP address, rather than its destination IP address.
You can configure more than one static multicast route. The device always uses the most specific route that matches a multicast source address. Thus, if you want to configure a multicast static route for a specific multicast source and also configure another multicast static route for all other sources, you can configure two static routes
Configure the distance keyword in the ip mroute command to specify the administrative distance, which the device uses to determine the best path for a route. When comparing multiple paths for a route, the device prefers the path with the lower administrative distance. To ensure that the default static route is used, configure a low administrative distance value. However, the device prefers directly connected routes over other routes, no matter what the administrative distance.
