Hi, ccielab#!

I setup virtual link on to kind of network. One kind of network is all frame-ra
ley pvc network, another kind of network include ISDN. I remember "virtual link
 on ISDN will let the ISDN never down" in the TCP/IP v1, and I saw it has happe
n. But when I show the virtual link status, I feel it's strange. So pls see the
 following:

Virtual Link OSPF_VL0 to router 10.1.1.1 is up
  Run as demand circuit
  DoNotAge LSA allowed.
  Transit area 0, via interface BRI0/0, Cost of using 1563
  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
  Message digest authentication enabled
      No key configured, using default key id 0

If I show the virtual link status on the all frame-relay network, I saw the fol
lowing:

Virtual Link OSPF_VL0 to router 10.1.2.1 is up
  Run as demand circuit
  DoNotAge LSA allowed.
  Transit area 1234, via interface Serial0/1, Cost of using 1
  Transmit Delay is 1 sec, State POINT_TO_POINT,
  Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
    Hello due in 00:00:07
    Adjacency State FULL (Hello suppressed)
    Index 2/3, retransmission queue length 0, number of retransmission 1
    First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)
    Last retransmission scan length is 1, maximum is 1
    Last retransmission scan time is 0 msec, maximum is 0 msec
  Message digest authentication enabled
      No key configured, using default key id 0

So why the adjacency state in ISDN virtual link network is not FULL. I have che
cked my config, I thinked no problem.

So pls give me you advice!!!

Thanks a lot!!!

Best Regards!!!
