Jason,
Your configuration is correct. However, if the scenario has two spokes,
problem arise.
Here it is:
R2/s0---302/203---s0/R1/s0---204/402---s0/R3
Where 302 is dlci on R2, 203 is dlci on R1, 204 is dlci on R1 402 is dlci on
R3.
On the s0 of R1, there are two DLCIs connecting to R2 and R3 respectively.
R1 is the frame relay hub, R2 and R2 are spokes.
Assume all the loopbacks of the three routers have been included in ISIS.
I also have clns map configured.
Before I turned up R3(or before I type in "frame relay map clns 402
broadcast" on R3)
R1and R2 can see each other's loopback.
But the minute I turned up R3(put in frame map clns command on R3), on R1, I
lost R2's loopback. On R2, I lost R1's loopback.
However, R1 and R3 can see each other's loopbacks now.
Following is my config:
R1:
interface Loopback0
ip address 11.0.0.1 255.0.0.0
ip router isis
!
interface Serial0
ip address 2.2.2.1 255.255.255.248
ip router isis
encapsulation frame-relay
frame-relay map clns 204 broadcast
frame-relay map clns 203 broadcast
frame-relay map ip 2.2.2.2 203 broadcast
frame-relay map ip 2.2.2.3 204 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
!
router isis
net 00.0002.1111.1111.1111.00
R2:
interface Loopback0
ip address 22.0.0.1 255.255.255.0
ip router isis
!
interface Serial0
ip address 2.2.2.2 255.255.255.248
ip router isis
encapsulation frame-relay
frame-relay map clns 302 broadcast
frame-relay map ip 2.2.2.1 302 broadcast
frame-relay map ip 2.2.2.3 302 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
!
router isis
net 00.0002.2222.2222.2222.00
!
R3:
interface Loopback0
ip address 33.0.0.1 255.255.0.0
ip router isis
!
interface Serial0
ip address 2.2.2.3 255.255.255.248
ip router isis
encapsulation frame-relay
frame-relay map clns 402 broadcast
frame-relay map ip 2.2.2.1 402 broadcast
frame-relay map ip 2.2.2.2 402 broadcast
no frame-relay inverse-arp
!
router isis
net 00.0002.3333.3333.3333.00
show ip route on R1 before turning up R3:
i L1 22.0.0.0 [115/20] via 2.2.2.2, Serial0
show ip route on R1 after turning up R3:
i L1 33.0.0.0 [115/20] via 2.2.2.3, Serial0
We can see R2's loopback disappear from R1's routing table.
Need your help on that.
Hans
