network 135.3.1.0 0.0.0.255 area 33
network 135.3.35.0 0.0.0.255 area 33
Everything works just fine except R1 is not participate in OSPF
networking. I type 'show ip ospf nei' doesnt show anything! I type
'show ip route', it only shows the connected interface....that's all.
Can anybody help me to solve this problem?

Sam,
It's too hard to follow the text config. So here are some general
help/guidelines
1) Remove all crypto/authentication to see if it works. You may
actually have to reboot the routers. If it works, you know where to
concentrate.
2) Make sure your normal areas are working OK before adding the virtual
link.
3) I don't think I saw any stubby areas so you should be OK there.
4) VL is part of area 0 so don't forget that all authentication applies
on it as well. This is the one most people tend to forget....adding
authentication to the VL.

Dear,
there is a mistake when configure virtual-link, example:
R1 R2
AREA 2 ----(X)---- AREA 1 ----(X)---- AREA 0
Router ID Router ID
1.1.1.1 2.2.2.2
R1: area 1 virtual-link 2.2.2.2
R2: area 1 virtual-link 1.1.1.1
Plz check
