This has to do with Cisco Bug CSCea40365:
"While redistributing ISIS routes into OSPF, the directly connected
routes [ISIS] are not getting redistributed into OSPF.
Workaround: use redistribute connected under 'router ospf'."
Although Cisco states that this bug only occurs in the redistribution
between IS-IS and OSPF, it has been found to occur when redistributing
IS-IS into all routing protocols. It also does not appear that this is
a 'Bug' that Cisco intends to fix.
To fix this redistribute your connected 163.1.12.0/24 network into RIP
on R2.

Is it the rightway to redistribute ISIS into RIP.
r1--------------------------r2-----------------------r3
r1 and r2 are running ISIS level 2, and r2 and r3 are running rip
version 2
subnet between r1 and r2 is 163.1.12.0/24. r1 (S0) 163.1.12.1/24 and r2
(s0)
163.1.12.2/24 over Frame-Relay.
subnet between r2 and r3 is 204.12.1.0/24 r2 (E0) 204.12.1.2/24 and r3
(E0)
204.12.1.3/24
Here is my configs:
R1
---------------------------------------------------
interface Serial0
ip address 163.1.12.1 255.255.255.0
ip router isis
encapsulation frame-relay
frame-relay map clns 102 broadcast
frame-relay map ip 163.1.12.2 102 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
isis circuit-type level-2-only
router isis
net 0c.0001.0001.0001.00
passive-interface Loopback0
R2
------------------------------------------------------
interface Ethernet0
ip address 204.12.1.2 255.255.255.0
!
interface Serial0
ip address 163.1.12.2 255.255.255.0
ip router isis
encapsulation frame-relay
frame-relay map clns 201 broadcast
frame-relay map ip 163.1.12.1 201 broadcast
no frame-relay inverse-arp
frame-relay lmi-type cisco
isis circuit-type level-2-only
router isis
net 0c.0001.0001.0002.00
redistribute rip
passive-interface Loopback0
!
router rip
version 2
redistribute isis level-2 metric
2-----------------------------redistributing
isis into rip
network 204.12.1.0
no auto-summary
R3 is receiving all the routes beyond R1, but is is not receiving the
route
163.1.12.0/24. 163.1.12.0/24 is a subnet used between r1 and r2, and has
ISIS
enabled on it.
Technically ISIS owns this route even it is a directly connected.
Any wrong with my configs.
Thanks
Ahmed
