Configuring Tasks
Configuring PIM
Because the MWR 1941-DC is used in a multicast PPP environment, you should configure the Protocol
Independent Multicast (PIM) mode of the FE interface.
To configure the PIM mode, use the following command while in interface configuration mode:
Command
Router(config-if)# ip pim {sparse-mode | sparse-dense-mode |
dense-mode [proxy-register {list access-list | route-map
map-name}]}
Configuring HSRP Support
In redundant configurations, the MWR 1941-DC uses Cisco IOS Hot Switch Routing Protocol (HSRP)
to control the active and standby routers. To use HSRP, you must configure the standby priority attributes
and the IP address of the virtual router. Priority is determined first by the configured priority value, and
then by the IP address. In each case a higher value is of greater priority.
If you do not plan to use the MWR 1941-DC in a redundant configuration, do not configure HSRP

Cisco MWR 1941-DC Router with the Cisco IOS IP-RAN Feature Set
Purpose
Configures PIM on an interface, where:
• sparse-mode—Enables sparse mode of
operation.
sparse-dense-mode—Treats the interface in
•
either sparse mode or dense mode of operation,
depending on which mode the multicast group
operates in.
dense-mode—Enables dense mode of
•
operation.
proxy-register—(Optional) Enables proxy
•
registering on the interface of a designated
router (DR) (leading toward the bordering
dense mode region) for multicast traffic from
sources not connected to the DR.
list access-list—(Optional) Defines the
•
extended access list number or name.
route-map map-name—(Optional) Defines
•
the route map.
