Dear experts,

Kindly resolve my queries reagrding OSPF given below

1- Why would I use the command "neighbour <ip> priority"?

2- I tried to send the summary routes from R1 over Virtual-link and GRE both
, but couldn't get summary route on R4

Scenario : R1----area0-----R2------area1-----R3------area2-------R4

I may have done any mistake, but plz let me know is it possible?

3- I have heared from some one that "area <id> range <address> <net mask>
not-advertise" filters type 1 LSA. Can any one plz elaborate it (i think
this relates with LSA type 3) and also tell me why would i use it, If i can
simple not advertise networks in my routing process, then definitely routes
would not be advertised

Thanks and regards,
