Exercise 2, Page 739 - OSPF to RIPv1.
The only way I can get this to work is change the mask on RB E1 to /28 (as
in part 1.), although the solution clearly states no need!
N.B. RB E1 is my S1/1
RB E0 is my S1/0
The ints on the left are loopbacks with IP OSPF NETWORK PONT_TO_POINT
RB routing table -
Gateway of last resort is not set
172.16.0.0/16 is variably subnetted, 10 subnets, 3 masks
O 172.16.1.160/28 [110/782] via 172.16.1.145, 00:41:32, Serial1/0
C 172.16.1.144/28 is directly connected, Serial1/0
O 172.16.1.128/28 [110/782] via 172.16.1.145, 00:41:32, Serial1/0
R 172.16.2.128/27 [120/1] via 172.16.1.98, 00:00:16, Serial1/1
O 172.16.1.224/28 [110/782] via 172.16.1.145, 00:41:32, Serial1/0
O 172.16.1.192/28 [110/782] via 172.16.1.145, 00:41:32, Serial1/0
R 172.16.2.32/27 [120/1] via 172.16.1.98, 00:00:17, Serial1/1
S 172.16.1.0/24 is directly connected, Serial1/0
C 172.16.1.96/27 is directly connected, Serial1/1
R 172.16.2.64/27 [120/1] via 172.16.1.98, 00:00:17, Serial1/1
A Debug IP Rip on RB shows :
03:43:24: RIP: sending v1 update to 255.255.255.255 via Serial1/1
(172.16.1.97)
03:43:24: RIP: build update entries - suppressing null update
Relevant config on B is :
interface Serial1/0
ip address 172.16.1.146 255.255.255.240
clockrate 128000
!
interface Serial1/1
ip address 172.16.1.97 255.255.255.224
clockrate 128000
router ospf 1
log-adjacency-changes
redistribute rip metric 1000000 subnets
passive-interface S1/1
network 172.16.1.146 0.0.0.0 area 0
!
router rip
redistribute ospf 1 metric 2
passive-interface S1/0
network 172.16.0.0
Any ideas?
