Chapter 4 Configuring the MWR 1941-DC in an IP-RAN
Configuring Fast Ethernet Interfaces
Configuring Routing Protocol Attributes
When used in the CDMA IP-RAN solution, the MWR 1941-DC must be configured to support the OSPF
routing protocol. To configure OSPF routing protocol attributes, do the following while still in interface
configuration mode:
Step 1
Enable OSPF Message Digest 5 (MD5) authentication.
Router(config-if)#
ip
ospf
message-digest-key
key-id
md5
key
Step 2
Specify the interval between hello packets that the Cisco IOS software sends on the interface.
Router(config-if)#
ip
ospf
hello-interval
seconds
Step 3
Set the interval at which hello packets must not be seen before neighbors declare the router down.
Router(config-if)#
ip
ospf
dead-interval
seconds
Configuring PIM
Because the MWR 1941-DC is used in a multicast PPP environment, you should configure the PIM mode
of the FE interface.
To configure the PIM mode, do the following while still in interface configuration mode:
Step 1
Enter the following 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 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.
Note
If you do not plan to use the MWR 1941-DC in a redundant configuration, do not configure HSRP
support and see
Configuring Redundancy, page 4-20
for information about using the router in a
stand-alone environment.
