Key Changes from IOSIGPs

Static RoutesBGP


Key Changes from IOS

Protocols are Address Family NeutralCLI IPv4Knobs to enable/disable things per Address Family

All configuration for IGPs is under protocol config modeNo routing commands under interfacesEnable IGP by specifying interfaces rather than ->843:, commands

More concise BGP configurationNeighbor basedFlexible templates for reuseRoute Policy Language for all route manipulation (BGP & IGP)

Pass prefix allowed if not later dropped!"## grants a ticket to defeat default dropExecution continues after pass

Set value changed, prefix allowed if not later droppedAny #$% at any level grants a ticketExecution continues after #$%Values can be set more than once

Done prefix allowed, stop executionDrop prefix is discarded

Explicit drop stops policy executionImplicit drop (if policy runs to end without getting a ticket)
