AREA1/VLAN1
--------------------
|e0 |e0
(R1) (R2)
|s0 |s0
| AREA0/FR |
| |
------------------
|s0.1 point to multipoint
(R3)
In this topology, If I have to send the traffic over
R1 to VLAN1 always and sent over R2 only in case R1
fails.. How do I do it. I have tried to give high IP
OSPF COST at the s0 of R1,s0.1 on R1 and e0 of R1, but
did not help. Always the traffic is going over only
R2. I have done interarea summarisation over R1 and R2
between area 1 and area 0. I have 'no ip route-cache'
over all the interfaces. The problem is when I shut
the interface e0 of R2 to check if the traffic now
takes the route through R1 to reach VLAN1, it does not
do that. The packets still try to go over to R2 and
get lost.
I am confused over the operation of 2 ABRs connecting
same NON-Backbone area (area1) to Backbone area
(area0).
Are there any special considerations for interarea
summarisation when you are using 2 ABRs to connect to
area O.
Any good place to read about these kinds of issues.
Thakns in advance.
