Hi experts,
I have a trouble with routing on ppp negotiated ip address interface.
*My topology:* R1(S0/1) ----- (S0/1)R2
R1: Loopback0: 10.1.1.1/24;
R2: Loopback0: 10.2.2.2/24
*My configuration:*
R1:
!
interface Loopback0
ip address 10.1.1.1 255.255.255.0
!
interface Serial0/1
*ip address negotiated*
encapsulation ppp
clock rate 2000000
no shutdown
!
R1#sh ip int brief
Interface IP-Address OK? Method Status
Protocol
Serial0/1 131.1.12.1 YES *IPCP*
up up
Loopback0 10.1.1.1 YES NVRAM up
up
!
R2:
!
interface Loopback0
ip address 10.2.2.2 255.255.255.0
!
interface Serial0/1
ip address 131.1.12.2 255.255.255.0
encapsulation ppp
*peer default ip address 131.1.12.1*
no shutdown
!
R2#sh ip int brief
Interface IP-Address OK? Method Status
Protocol
Serial0/1 131.1.12.2 YES manual up
up
Loopback0 10.2.2.2 YES NVRAM up
up
!
R2#ping 131.1.12.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 131.1.12.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/43/152 ms
*Problem with routing:*
- RIPv2
R1 & R2:
!
router rip
version 2
network 10.0.0.0
network 131.1.0.0
no auto-summary
!
Result: RIP don't exchange database.
Resolve: R1 & R2
!
router rip
no validate-update-source
!
*RIP operates normally.*
- OSPF
R1 & R2:
!
router ospf 1
network 0.0.0.0 255.255.255.255
!
Result: OSPF don't establish adjacency
R1#debug ip os adj
*Mar 1 00:38:28.627: OSPF: Rcv pkt from 131.1.12.2, Serial0/1, area
0.0.0.0: src not on the same network
*Mar 1 00:38:29.991: OSPF: Rcv pkt from 131.1.12.2, Serial0/1, area
0.0.0.0: src not on the same network.
*Resolve:* *????? How to establish adjacency between R1 and R2*
- EIGRP: Normally
- BGP: Normally.
*Conclusion:* I need your help to establish adjacency between R1 and R2 (R1
serial obtains ip address from R2).
Thanks in advance.
