Can an ABR router in non-area 0 router generate a default summary route in to other area?

[Giuseppe Larosa]

Hello @Aneek ,

in order to operate as an ABR a router must have an interface in area 0.

In other terms a device having some interfaces in area X and another subset of interfaces in area Y will not act as an ABR by generating LSA type 3 between the two area X and Y.

the connection to area 0 can be provided by a virtual link going via a standard area but at least one link in area 0 is needed to act as an ABR.

Hope to help

Giuseppe
