Hie Experts,
I came across a question that If I have a multi area ospf network,
AREA 0 --- AREA 1 --- AREA 3
If I configure a virtual link from area 3 to area 0 using AREA 1 as
transit. area 1 virtual-link 4.4.4.4
1- now, what happens if the router 4.4.4.4 in bw area 0 and 100 goes down
?? do I have to reconfigure the virtual link ?
2- What happens if the DR router in area 0 goes down, and an election
takes place, so the BDR on area 0 becomes the DR.do I have to reconfigure
the
virtual link??
My understanding in this regard is
Ans 1- If router 4.4.4.4 down the link will down and untill u have some
backup link configure , area 3 wil be dosconnected(Kindly shed some views
on how to configure backup Virtual links).
Ans 2- DR / BDR have no effect on Virtual links, ABR wil calc the current DR
and fwd LSAs to that.
Kindly correct me if i m wrong somewhere.
Regards
Hammad
