Usage
Specifying the ABR type allows better interoperation between different
implementations. This command is specially useful in a multi-vendor environment.
The different ABR types are:
•
Cisco ABR Type: By this definition, a router is considered an ABR if it has more
than one area actively attached and one of them is the backbone area.
•
IBM ABR Type: By this definition, a router is considered an ABR if it has more
than one area actively attached and the backbone area is configured. In this
case the configured backbone need not be actively connected.
•
Standard ABR Type: By this definition, a router is considered an ABR if it has
more than one area actively attached to it.
