Hi guys
I've just come across a really strange situation and I don't know if it's a
bug or not. this is the layout below
area 3-------- r 5-------area 1--------r2
| |
| |
| area 0
| |
| |
isdn--------area 2----- r3
I don't know how well the above diagram looks to you all but I'll try to
explain whats happening. Ospf is working fine I have all the relevant
virtual inks to maintain connectivity, i.e r2 -r5 across area 1 and r3 - r5
across area 2, also i have ip ospf demand circuit on the isdn. Now the
problem;
If I use the backup interface command on r5 for area 1 it never brings the
isdn up on a failure with the interface on r5 connected to area 1. if i
don't use backup interface it works fine.
so my question is do I just rely on ospf to bring the isdn up and not use
backup interface at all ??? or am i asking a stupid question !!!!
As you have probably gathered from all my questions recently that I am in
the lab preparing for my next attempt
cheers
