Routing between Ethernet & Token Ring

[shabbs]

Can anyone assist? I am trying to configure routing between an Ethernet subnet and a Token Ring subnet using a Win2000 server that contains both Ethernet& Token Ring network cards. Several PC's are sat on both subnets (i.e. they contain both an Ethernet card and a Token Ring card). All PC's on the Token Ring subnet can communicate with each other. All PC's on the ethernet subnet can communicate with each other

Subnet 1 - Ethernet 192.168.0.0, SM 255.255.255.0
Subnet 2 - Token ring 10.72.80.0, SM 255.255.255.0

The network cards on the Win2000 router are configured as follows:-

Ethernet IP address - 192.168.0.9
Ethernet SM - 255.255.255.0
Default Gateway - 192.168.0.9

Token Ring IP address - 10.72.80.16
Token Ring SM - 255.255.255.0
Default Gateway - 10.72.80.1

I have enabled IP Forwarding on the Win2000 router
I am trying to ping a machine on the Token Ring subnet from a PC (IP add: 192.168.0.8, SM 255.255.255.0, DG 192.168.0.9) on the Ethernet subnet. This PC contains only an ethernet card.
I can ping the Token Ring card on the Win2000 router (10.72.80.16) from the Ethernet only PC and I can ping all other PC's (via their token ring address) that are sat on both Token Ring and Ethernet subnets. I cannot ping (from the ethernet subnet) any PC (via their token ring address) on the Token Ring subnet that only contains only a Token Ring card.


Can anyone please advise??

You've lost me a bit there but one thing I did notice is that you have two default gateways on your router. You can only have one.

Set the router up as follows:

Ethernet:
ip = 192.168.0.9
sm = 255.255.255.0
gw =

Token Ring:
ip = 10.72.80.16
sm = 255.255.255.0
gw = 10.72.80.16

Once you've made the changes type: route print
Make sure there are entries for:
192.168.0.0 mask 255.255.255.0 192.168.0.9
10.72.80.0 mask 255.255.255.0 10.72.80.16

If either of these are missing add it using the following command:

Eg.

route add -t 10.72.80.0 mask 255.255.255.0 10.72.80.16

If you have other routers on your WAN you will have to add routes to those as well to make them aware of your new router.


Hope this helps,
