Enterasys Networks CSX5500, CSX6000, CSX7000 manual IP RIP Output Processing on a WAN Interface

USER’S GUIDE

LAN 131.1.0.0

Router 1 131.1.1.16

128.1.1.16

CSX5500

128.1.1.1

1.Determine if the CyberSWITCH has learned the route to 131.1.0.0 from Router 1. On the administration console type:

ip route <return>

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
