OSPF Virtual Links

I am having a difficult time finding information regarding a detailed
explanation of OSPF virtual links with regards to route summarization on the
remote end of the virtual link router.

I am working on a practice lab that:

(area5) R1 --(area0)--- R2 ----(area1) ---R3 ---(area3) --- R4

The requirement is to connect R2 to R3 with a virtual link to allow area5
routes to be propagated to R4.
1.1.0.0/24
1.1.1.0/24
1.1.2.0/24
1.1.3.0/24

The routes show up on R4 as expected, but the next requirement is to summarize
the routes at R3 so that it shows up as 1.1.0.0/22 on R4.

Since R3 is now a member of Area0, I would think i can use
area 0 range 1.1.0.0 255.255.252.0

But,this doesn't work.
It seems that there are some peculiar characteristics regarding virtual links
and area 0, but there isn't much documentation outside of the rudimentary
explanation and troubleshooting commands.

Thanks in advance for everyones help,

Chris
