Ticket 1 – OSPF Authentication

May 6th, 2018 in TSHOOT v2 Go to comments

1.Client is unable to ping R1’s serial interface from the client.

Problem was disable authentication on R1, check where authentication is not given under router ospf of R1. (use ipv4 Layer 3)

Configuration of R1:

interface Serial0/0/0
 description Link to R2
 ip address 10.1.1.1 255.255.255.252
 ip nat inside
 encapsulation frame-relay
 ip ospf message-digest-key 1 md5 TSHOOT
 ip ospf network point-to-point
!
router ospf 1
 router-id 1.1.1.1
 log-adjacency-changes
 network 10.1.2.0 0.0.0.255 area 12
 network 10.1.10.0 0.0.0.255 area 12
 default-information originate always
!

Configuration of R2:
interface Serial0/0/0.12 point-to-point
 ip address 10.1.1.2 255.255.255.252
 ip ospf authentication message-digest
 ip ospf message-digest-key 1 md5 TSHOOT
!

Answer: on R1 need command ip ospf authentication message-digest”

Ans1) R1
Ans2) IPv4 OSPF Routing
Ans3) Enable OSPF authentication on the s0/0/0 interface using the “ip ospf authentication message-digest” command.

Note:

There are two ways of configuring OSPF authentication:

interface Serial0/0/0
  ip ospf message-digest-key 1 md5 TSH00T
!
router ospf 1
  area 12 authentication message-digest

OR

interface Serial0/0/0
  ip ospf authentication message-digest
  ip ospf message-digest-key 1 md5 TSH00T

So you have to check carefully in both interface mode and “router ospf 1”. If none of them has authentication then it is a fault.

    is the answer correct for ticket 1? because there is no network command for the serial interface how is it participating in OSFP!
