[att-sgcops]

can some one tell me the difference of these 2 commands?

area 10 nssa default-information-originate

area 10 nssa no-summary

since what I know is they all generate default route into area 10....

helllo ,

i have seen some detail in the cco document,

Option default-information-originate is used to generate a Type 7 default into the NSSA area. This keyword takes effect only on NSSA ABR or NSSA Autonomous System Boundary Router (ASBR). and

Option no-summary allows an area to be a not-so-stubby area but not have summary routes injected into it.
