[c-nsp] OSPF signalled restart question

[Hank Nussbacher]

I have 2 routers connected via a gateD cluster.  rtr1 has area 200 and rtr2 
has areas 0 & 100.  In between is the gateD which has areas 0 & 200:

rtr1:

interface Loopback1
  ip address 172.16.1.252 255.255.0.0
!
interface FastEthernet0/0
  ip address 10.20.20.50 255.255.255.0
  ip ospf message-digest-key 1 md5 abc
!
interface Vlan80
  ip address 10.80.80.3 255.255.255.0
  ip ospf message-digest-key 1 md5 abc
!
router ospf 15
  log-adjacency-changes
  area 200 authentication message-digest
  redistribute connected subnets
  passive-interface default
  no passive-interface FastEthernet0/0
  no passive-interface Vlan80
  no passive-interface Loopback1
  network 10.20.20.0 0.0.0.255 area 200
  network 10.80.80.0 0.0.0.255 area 200

rtr2:

interface Loopback1
  ip address 172.16.1.254 255.255.0.0
!
interface FastEthernet0/0
  ip address 10.10.10.1 255.255.255.0
  ip ospf message-digest-key 1 md5 abc
!
interface Vlan30
  ip address 10.30.30.1 255.255.255.0
!
interface Vlan40
  ip address 10.40.40.1 255.255.255.0
  ip ospf message-digest-key 1 md5 abc
!
router ospf 5
  log-adjacency-changes
  area 0 authentication message-digest
  area 100 authentication message-digest
  redistribute static subnets
  passive-interface default
  no passive-interface FastEthernet0/0
  no passive-interface Vlan30
  no passive-interface Vlan40
  no passive-interface Loopback1
  network 10.10.10.0 0.0.0.255 area 0
  network 10.30.30.0 0.0.0.255 area 0
  network 10.40.40.0 0.0.0.255 area 100

gateD:
router ospf 1
     restart-enable
     restart-type signaled
     router-id 10.10.10.100
     network 10.10.10.0 0.0.0.255 area 0.0.0.0
     area 0.0.0.0 authentication md5 1 [hidden]
     area 0.0.0.200 priority 255
     network 10.20.20.0 0.0.0.255 area 0.0.0.200
     area 0.0.0.200 authentication md5 1 [hidden]
     exit

Tracking 10.40.40.0 that exists on rtr2 - it appears on rtr1.  But as soon 
as a signalled restart occurs, the network 10.40.40.0 - and only 10.40.40.0 
disappears from rtr1.  All other networks from rtr2 appear fine on rtr1.

So what bit of OSPF logic am I missing?

Thanks,
Hank
