USER’S GUIDE

444 CyberSWITCH

1. Determine if the CyberSWITCH has learned the route to 131.1.0.0 from Router 1. On the

administration console type:

ip route

If the following route entry is displayed among other route entries, the IP RIP input processing

is operational. The ‘P’ (Protocol) field should have ‘R’, which indicates that the entry was

learned via RIP.

Destination Subnet-Mask Next Hop Mtr T/P TTL IF AGE

131.1.0.0 255.255.0.0 128.1.1.16 1 R/R 999 n nnn

2. If the route is NOT displayed, try the following:

a. Verify that the IP RIP Receive Control is set to the proper RIP version that the Router is

using. Refer to page 443 for instructions regarding check RIP versions.

b. Enter the

ip rip stats

administrative console command. Look for the counter

IfStatRcvResponses for the interface, which show the number of RIP update

messages received on the interface. If the total number of these counters is 0, check the

Router to verify that it is configured to send IP RIP update messages.

c. Also look for the IfStatRcvBadPackets and

IfStatRcvBadRoutes counters.

• If these counters are not 0, there may be something wrong with the Router.

• If these counters are 0, there is an unexpected condition present within the

CyberSWITCH software. Contact Customer Support.

IP RIP OUTPUT PROCESSING ON A WAN INTERFACE

To verify that IP RIP Output Processing (routes advertisement) is properly operational on a WAN

interface, the IP RIP processing must be successfully initialized.

Below is an example of a configuration used to verify IP RIP output processing on a WAN interface.

It uses IP addresses specific to the example. Substitute the IP addresses of your network when you

LAN 131.1.0.0
