frame relay switch

liven

I have setup a frame relay switch

we will call it switch A


switch A conncets to router B and Router C

switch A (really a router) has no IP address.

Router B serial sub int ip: 192.168.3.2
router C serial sub int ip: 192.168.3.3

Router B and C can ping each other

But I can not ping or telnet from switch A to router B and Router C.

Now keep in mind that switch A is really a router.

So how do I setup a frame relay router/switch so I can ping/telnet to the point to point links (router b and C)?

First thought in my mind was this might work if you create subinterfaces on the FR switch.
But after playing around with the idea and trying to map sub-intf to DLCI numbers in my lab. I don't believe this is possible through a FR switching manner. The only other way I can think of if you really want to do this is by creating a lan segment for the FR switch and the 2 routers through ethernet ports. I can't test this at the moment as the FR switch I am using doesn't have an ethernet port.

Thanks big horn

I really just wanted to make sure that I am not going crazy (because I can't get to the point to point links).


What I did was create a back door of sorts.

Granted I can not get to the end points of the frame relay from the frame relay switch.

But I setup a switch and connected it to ethernet ports on legs of the frame relay.

Not perfect but at least I can get to the routers remotely.

If all you want to do is be able to remote access the routers, why don't you use console for one of your end routers and then telnet to the other one? Once you configure your FR switch, you do your routing configs on the end routers, so you dont need an active connection to the FR except for debugging.

In reality, that's how it works anyways, the FR switch(s) sit with the ISP/Telco, you only get a DLCI # and your own end routers to configure and maintain.
