abr-type
Use this command to set an OSPFv3 Area Border Router (ABR) type.
Use the no parameter with this command to revert the ABR type to the default setting (cisco).
Specifying the ABR type allows better functioning in a multi-vendor environment. The ABR types are:
• Cisco (RFC 3509): A router is considered an ABR if it has more than one area actively attached and one of them is the backbone area.
• IBM (RFC 3509): 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 (RFC 2328): A router is considered an ABR if it has more than one area actively attached to it.
