Route Tagging and Multiple OSPF Processes/Instances

Cisco IOS Software currently allows several OSPF processes. This is not possible with Zebra or GateD. Route tagging is only possible for the entire OSPF domain in GateD, whereas Cisco IOS Software supports tagging in context with redistribution and the domain-tag OSPF command.
