Point to Point T1 between two routers

[esfandiarfard]

Need help please. Have a PPP on two 2800 routers that has been working for couple of months now. One subnet is 172.15.x and the other is 192.168.2.x , I can ping all devices on both sides as long as they are on VLAN1 but I try other VLANS , ping fails. Mainsite has 5 VLANS configured and I like to get to those. I hope I have provided enough information

Saied,

Please tell us more about the main site network layout. You mentioned you have 5 VLANs, what's the device performing the inter-vlan routing ? Can those VLANs ping their local 2800 router ?

All my vlans can ping local 2800 router fine but get a TTL timeout when pinging the 2800 router on the other side of the point to pint connection T1.

The 3750 switch does all the inter-vlan routing. Thank You.

Are you using a routing protocol between the two routers; if not, are you using static routes? Are the networks/VLANs being advertised between the two routers? Are subinterfaces setup on the mainsite router for the five VLANs?

I would say 3750 switch needs bunch of static routes - one for each VLAN with def gw poining to the 2800 box. Then in the 2800 box same thing, unless you use some routing proto. Then none of this will be required and thigns will work automatically
