Hi Guys
In below topology , The network 88.88.88.0 which redistributed on SW2 in
NSSA is not translating by R5 NSSA (border router). Can you please let me
know why is it not advertise to R3
R3 s1/0-------- Frame Relay -----------s1/0 R5 E0/0---------------- NSSA
---------------SW2 (loopback 88.88.88.88 redistribute into OSPF : NSSA)

R3 : 155.1.0.3 (S1/0)
R5 : 155.1.0.5 (S1/0) and 155.1.58.5 (E0/0)
SW2 : 155.1.58.8 (VLAN 58)
router-id for R5 is 150.1.5.5 , R3 : 150.1.3.3 , SW2 : 150.1.8.8
