RIPng

RIPng provides a compact IPv6 distance-vector model. It is useful when a lab needs simple IPv6 dynamic routing without the complexity of OSPFv3 or BGP.

Support level

Area	Level	Notes
IPv6 RIP routes	Behaviour model	Computes IPv6 reachability with hop-count metrics.
Interface activation	Supported	RIPng is enabled on interfaces.
Hop-count metric	Supported	Lower metric wins; unreachable routes are suppressed.
Packet fidelity	Not modelled	Behaviour is solver-based.

Standards coverage

Standard	Coverage	Notes
RFC 2080	Behaviour model	RIPng distance-vector semantics for IPv6.

Feature matrix

Feature	Status	Notes
RIPng process	Supported	Named process / interface activation where parsed.
Interface enable	Supported	Participating IPv6 interfaces advertise connected prefixes.
Route installation	Supported	Installs RIPng routes into the IPv6 RIB.
Authentication	Not modelled	RIPng authentication extension behaviour is out of scope.

Vendor command matrix

Command	IOS-style	Junos-style	VyOS-style	Notes
ipv6 rip NAME enable	Supported	n/a	Partial	Interface activation.
show ipv6 route rip	Supported	Partial	Partial	RIPng-learned routes.

Behaviour notes

RIPng routes are solved from the topology graph, not learned through a stream of multicast updates. This keeps training scenarios replayable.

Examples

Canonical example

configure terminal
interface GigabitEthernet0/0
 ipv6 address 2001:db8:12::1/64
 ipv6 rip CORE enable
end
show ipv6 route rip

Vendor styles

IOS-style

Known limits

Packet exchange fidelity, authentication extensions, and vendor timer details are not part of the current model.
