Let’s check frame-relay mapping! Make sure the frame map is in active

R1(config-if)#do sh fram map

Serial0/0.12 (up): point-to-point dlci, dlci 102(0x66,0x1860), broadcast

          status defined, active

Serial0/0.13 (up): point-to-point dlci, dlci 103(0x67,0x1870), broadcast

          status defined, active

R2(config-if)#do sh fram map

Serial0/0.12 (up): point-to-point dlci, dlci 201(0xC9,0x3090), broadcast

          status defined, active

R3(config-if)#do sh fram map

Serial0/0.13 (up): point-to-point dlci, dlci 301(0x12D,0x48D0), broadcast

          status defined, active

Now let’s activate OSPF in all router

R1(config-if)#router ospf 1

R1(config-router)#router-id 1.1.1.1

R1(config-router)#net 1.1.1.1 0.0.0.0 are 0

R1(config-router)#net 12.12.12.1 0.0.0.0 are 0

R1(config-router)#net 13.13.13.1 0.0.0.0 are 0

R2(config-if)#router ospf 2

R2(config-router)#router- 2.2.2.2

R2(config-router)#net 2.2.2.2 0.0.0.0 are 0

R2(config-router)#net 12.12.12.2 0.0.0.0 are 0

R3(config-if)#router ospf 3

R3(config-router)#router- 3.3.3.3

R3(config-router)#net 3.3.3.3 0.0.0.0 are 0

R3(config-router)#net 13.13.13.3 0.0.0.0 are 0

Check ip ospf type and routing table

R3(config-router)#do sh ip rou

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

     1.0.0.0/32 is subnetted, 1 subnets

O       1.1.1.1 [110/65] via 13.13.13.1, 00:01:34, Serial0/0.13

     2.0.0.0/32 is subnetted, 1 subnets

O       2.2.2.2 [110/129] via 13.13.13.1, 00:01:34, Serial0/0.13

     3.0.0.0/32 is subnetted, 1 subnets

C       3.3.3.3 is directly connected, Loopback0

     12.0.0.0/24 is subnetted, 1 subnets

O       12.12.12.0 [110/128] via 13.13.13.1, 00:01:34, Serial0/0.13

     13.0.0.0/24 is subnetted, 1 subnets

C       13.13.13.0 is directly connected, Serial0/0.13

R3(config-router)#do sh ip ospf int s0/0.13

Serial0/0.13 is up, line protocol is up

  Internet Address 13.13.13.3/24, Area 0

  Process ID 3, Router ID 3.3.3.3, Network Type POINT_TO_POINT, Cost: 64

  Transmit Delay is 1 sec, State POINT_TO_POINT

Make sure the ping is ok

R3(config-router)#do ping 2.2.2.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
