Godswill, did you rewrite the RFC for IPv4? I didn't think "263" was a
valid value for an IP address... ;-)
"I believe should be:
Interface ethernet0/0.263
Encapsulation dot1q 263 native
Ip address 193.7.6.263 255.255.255.0"
Magmax, don't just change the last octet, otherwise both interfaces will
still be in the same subnet, which is probably not what you want to do. I'm
sure you probably just mixed up the interface configs?

One of your ip addresses is wrong:
> Interface ethernet0/0.263
> Encapsulation dot1q 263 native
> Ip address 193.7.6.6 255.255.255.0
I believe should be:
Interface ethernet0/0.263
Encapsulation dot1q 263 native
Ip address 193.7.6.263 255.255.255.0

This my personal opinion and preference:
1. Advertise into Area 0
2. If there is no Area 0 in that Router, advertise into another area present
in that Router.
3. Redistribute with connected route-map ****
Since, option 3 have some caveats, I will use it with caution. However, if
you understand the caveats and are ready to do the extra configurations
necessary when redistributing between OSPF and another IGP on that router,
then use option 3.
However, if the task did not restrict me and OSPF Area 0 is available, I
will advertise it into area 0 and move on, with bordering myself about my
routing been broken.
