Wish my books told me about a Frame Relay Switch....

So I'm over here configuring Frame Relay and I got both ends figured out then the curve ball I need a frame relay switch. So I used one of the 2600's with the 4 port serial card as a frame-switch.

Now I'm having the hardest time figuring out why the frig OSPF won't enable between the links, I've tried multi and PPP on both ends but they just won't pop, the lines and protocols are up/up on both ends so that's good.

Maybe someone else can see something I'm not, been at this since 5:30pm.

also I get mixed reports online that says the frame switch can be a DTE or DCE on the router aka the switch, and then you just issue the frame-relay intf-type dce/dte, but my brain si fried, not sure I'm seeing the issue....

Do you have IP connectivity?

Deathmage

That's the thing I says up/up but I can't ping, not even locally across any of the frame links.

Makes me ponder if I need vlans on the frame relay interfaces.

It's probably something stupid...

Simrid

Possibily adding sub interfaces on your hub may help, on for a reply for each host.

I prefer using the interface dlci command when doing FR..

I'll give the sub interface a try this evening

I did try to reinvent the wheel and not use subinterfaces on the routers, but soon realized all my learning material from notes all had subinterfaces for multipoint and point-to-point so perhaps that's significant on the frame switch.

I just looked over the configs and the routing is correct for OSPF and as are the IP addresses. Has to be literally one or two settings.

Simrid

Not sure if it will make much difference on the frame switch itself. Worth a shot. Make sure the interfaces of the routers have a DLCI assigned to their interfaces.

On the routers which aren't the FR switch:

You then would need to do interface serial 1/0.1 point-to-point command, as the sub interface allows for a theorical point to point link to the hub. In there you can set the frame map and use the frame-relay interface-dlci x command which applies the DLCI to the sub interface.

Let me know how you get on!

You then would need to do interface serial 1/0.1 point-to-point command, as the sub interface allows for a theorical point to point link to the hub. In there you can set the frame map and use the frame-relay interface-dlci x command which applies the DLCI to the sub interface.

Let me know how you get on!

The kicker as to why I used multipoint vs PPP was because from the videos I did only mutlipoint can do OSPF or EIGRP broadcasts, can PPP do that too? - Jeremy on CBT Nuggets said Multipoint can only doing OSPF and EIGRP.

See I tried the "frame-relay interface-dlci x" but then it made another subinterface, so say the 2821 on say S0/3/0 has a DLCI of 130 and the other side of the relay on the 2600 on the opposite side of the relay switch the DLCI is 930. Too me this would only be applied in a frame-relay route but once I got that second drop down subinterface I was scratching my head a little bit, what number would need to go in the name of the subinterface and then what number would go inside of the subinterface.

IE:

Obviously this would go under the interface affected, will mess around with the S0/0.xxx subinterfaces to see if this makes a different, but I know the below commands go under the serial interfaces, this much I know...

2821-CORE-2 (130 is local to the 2821, the opposite side of the 930)

2821-CORE-2(config-if)# frame-relay interface-dlci 130
2821-CORE-2(config-fr-dlci)# frame-relay interface-dlci 930

2600A-Bottom (930 is local to the 2600, the opposite side of 130)

2600A-Bottom(config-if)# frame-relay interface-dlci 930
2600A-Bottom(config-fr-dlci)# frame-relay interface-dlci 130

Like this?

Deathmage

YAY BABY!!!!!!!

Peristance pays offf, got a (4) area OSPF to work correctly!!!!!!!!

so F*cking hate Frame Relay but I'm getting a bottle of scotch and I don't even drink scotch!!!!!!

tomorrow I move onto RSTP and PVST at the Area 1 layer, hopefully that not as annoying as Frame Relay..
