[j-nsp] OSPF LSAs

[Stefan Mink]

Hi,

I've a combination of OSPF LSAs in the database of a router
which looks strange to me, maybe somebody can give me a hint:

 > show ospf database asbrsummary

     OSPF link state database, area 0.0.0.4
  Type       ID               Adv Rtr           Seq      Age  Opt  Cksum  Len
ASBRSum *AAA.BBB.CCC.1    AAA.BBB.CCC.30   0x80000b84  2783  0x2  0x440a  28
ASBRSum *AAA.BBB.CCC.2    AAA.BBB.CCC.30   0x80000b44  2755  0x2  0x1f64  28
ASBRSum *AAA.BBB.CCC.35   AAA.BBB.CCC.30   0x80000037  2727  0x2  0x373f  28

 > show ospf database extern
     OSPF AS SCOPE link state database
  Type       ID               Adv Rtr           Seq      Age  Opt  Cksum  Len
Extern   0.0.0.0          AAA.BBB.CCC.1    0x80005cc3  2324  0x2  0x8a94  36
Extern   0.0.0.0          AAA.BBB.CCC.2    0x80007f86   379  0x20 0xd148  36


Can somebody explain to me why there is a ASBR-Summary-LSA
for AAA.BBB.CCC.35 in the database, but no external LSA from
that router.

Maybe I just need a lesson in OSPF but so far an ASBR was a router, which
imports a route into OSPF, thus creates an external LSA...
