Hi..Everyone..
I'm studying IS-IS now..
So i have a question about it..
How can i solve this problem ??
Thanks..
-----------
My Diagram
____________
|-------------OSPF------------|-----------IS-IS------------|
R1-(e0 1.1.1.1)-(e0 1.1.1.2)-R2-(e1 2.2.2.1)--(e1 2.2.2.2)-R3
-R1'E0 & R2'E0 is covered with a OSPF
-R2 & R3 is connected with a IS-IS Type 1
So the configuration is
R1>
router ospf 1
network 1.1.1.1 0.0.0.0 area 0
R2>
router ospf 1
network 1.1.1.2 0.0.0.0 area 0
!
router isis
net 01.2222.2222.2222.00
is-type level-1 **
interface e1
ip add 2.2.2.1 255.255.255.0
ip router isis **
R3>
router isis
net 01.3333.3333.3333.00
is-type level-1 **
interface e1
ip add 2.2.2.2 255.255.255.0
ip router isis **
=> So, The IS-IS Type between R2 & R3 is a Level 1.
-----------
Question!!
-----------
-On R2, Redistribute OSPF into ISIS as L-2 routes
-----------
My solution
-----------
=>On R2, i redistributed OSPF into IS-IS as Level2 like this
router isis
net 01.2222.2222.2222.00
is-type level-1
redistribute ospf 1 metric-type external level-2 match internal metric 10 **
=> But On R3, there is no 1.1.1.0/24-routes with IS-IS L2-type..!!!!!
=> Because The ISIS-type is a Level 1, I cannot redistribute ospf-routes as
ISIS L2-routes ??
=> There is no method ??? How can i solve this problem ???
