Hi Group,
- the question ask to configure area 0 with md5 authentication
- the virtual link transits another area 100, which not asked for
authentication
I does not configure virtual-link authentication, it is still up, and full
adjacent.
core#sh ip ospf virtual-links
Virtual Link OSPF_VL0 to router 10.1.1.1 is up
Run as demand circuit
DoNotAge LSA allowed.
Transit area 100, via interface Serial1/1, Cost of using 10
Transmit Delay is 1 sec, State POINT_TO_POINT,
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
Hello due in 00:00:06
Adjacency State FULL (Hello suppressed)
Index 1/2, retransmission queue length 0, number of retransmission 0
First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)
Last retransmission scan length is 0, maximum is 0
Last retransmission scan time is 0 msec, maximum is 0 msec
Message digest authentication enabled
No key configured, using default key id 0
R4#
My question is that how to know whether we should configure authentication
for virtual link?
Adv. Thanks,
Ed.
