How to deal with multiple same type7 LSAs in NSSA ABR/ASBR ?

R1-----------R2----------------------R3

     Area0       Area1(NSSA)

Multiple same type7 lsa exist in NSSA area DB. One is from nssa interal router R3 (redistribute static). The other is created by ABR(R2) itself ( redistribute the same static routes which point to null0). Due to ABR is also ASBR the redistruted routes' P bit is 0.

My question is:

1. Does ABR translate type7 LSA which is from R3?

2. If yes, how to fill in FA address in type5 LSA?

Thank you in advance!

Hi Gi,

The ABR is also the ASBR  and it will translate the type 7 into a type 5.

To change the fowarding address you can manipulate that by using

"area 1 nssa translate suppress-lsa" command
