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.
Example To configure the ABR type as ibm, use the following commands:
awplus# configure terminal
awplus(config)# router ospf 100
awplus(config-router)# ospf abr-type ibm

cisco Specifies an alternative ABR using Cisco implementation (RFC 3509).
This is the default ABR type.
ibm Specifies an alternative ABR using IBM implementation (RFC 3509).
standard Specifies a standard behavior ABR (RFC 2328).
