Step 1 Verify that you have the Network Information Data Sheet (NIDS) applicable to this
Cisco BTS 10200 Softswitch. If necessary, contact your network administrator to verify that you have
the correct NIDS.
Step 2 On default gateway interfaces for Network 1 and Network 2 (as defined in the NIDS) enable IRDP using
the following commands:
config t
interface <Fast Ethernet interface number (see NIDS)>
ip irdp
ip irdp maxadvertinterval 4
ip irdp minadvertinterval 3
ip irdp holdtime 10
Step 3 Validate the configuration by performing the following command on both CA/FS hosts and both EMS
hosts:
login as root
#netstat -rn
Step 4 View the display and verify that each default route was populated dynamically by IRDP.
Verify IRDP Functions
Follow these steps to verify that IRDP is functioning properly on the network:
CA Side A
Perform Step 1 through Step 11 on CA Side A.
Step 1 Login to CA Side A as root.
Step 2 Display the IRDP daemon status by entering the following command:
ps -ef|grep in.rdisc
Step 3 View the display and verify that each default route was populated dynamically by IRDP. The display
should include the following information: /usr/sbin/in.rdisc -s -f. (This indicates that IRDP is running
properly.)
Step 4 Display the routing table by entering the following command:
netstat -rn
Step 5 Verify that the routing table shows two default routes, one on interface NET 0 and one on NET 1.
Step 6 Unplug the interface NET 0 link at the back of CA Side A.
