Brian, is this LSA originated by the ABR/ASBR or from an ASBR inside the
NSSA? The RFC specifies that LSA originated by an ASBR that is also an
ABR must clear the P-bit to prevent the LSA from translated by another
ABR.
Cheers,
Marcus.

More info to add to this. Basically the P-bit is not being set, and so
the
Type 7 -> Type 5 translation is not taking place:
cygnus#show ip ospf database nssa-external 207.254.220.224
OSPF Router with ID (207.254.193.53) (Process ID 10)
Type-7 AS External Link States (Area 10)
Routing Bit Set on this LSA
LS age: 94
Options: (No TOS-capability, No Type 7/5 translation, DC)
LS Type: AS External Link
Link State ID: 207.254.220.224 (External Network Number )
Advertising Router: marshall-gw.shreve.net
LS Seq Number: 80000001
Checksum: 0x7FC0
Length: 36
Network Mask: /29
Metric Type: 2 (Larger than any link state path)
TOS: 0
Metric: 20
Forward Address: 208.242.79.1
External Route Tag: 0
This router is an ASBR (since its redistributing some statics/connected
of
its own), and its an ABR for the NSSA (area 10). If anyone can shed
further light on why the P-bit may not be being set, and how I could
change that behavior, that would be great. I am currently approaching
this as if it were a bug, and playing IOS roulette.
