NetworkInstances.NetworkInstance.Afts¶ Bases:
EntityClass Hierarchy:
NetworkInstancesNetworkInstanceAftsThis class represents configuration data.
The abstract forwarding tables (AFTs) that are associated
with the network instance. An AFT is instantiated per-protocol
running within the network-instance - such that one exists for
IPv4 Unicast, IPv6 Unicast, MPLS, L2 forwarding entries, etc.
A forwarding entry within the FIB has a set of next-hops,
which may be a reference to an entry within another table -
e.g., where a Layer 3 next-hop has an associated Layer 2
forwarding entry.
-
ipv4_unicast¶ The abstract forwarding table for IPv4 unicast. Entries within this table are uniquely keyed on the IPv4 unicast destination prefix which is matched by ingress packets. The data set represented by the IPv4 Unicast AFT is the set of entries from the IPv4 unicast RIB that have been selected for installation into the FIB of the device exporting the data structure
type:
Ipv4Unicast
-
ipv6_unicast¶ The abstract forwarding table for IPv6 unicast. Entries within this table are uniquely keyed on the IPv6 unicast destination prefix which is matched by ingress packets. The data set represented by the IPv6 Unicast AFTis the set of entries within the IPv6 RIB that
type:
Ipv6Unicast
-
policy_forwarding¶ The abstract forwarding table for policy-based forwarding entries. Since multiple match criteria can be utilised within a policy-based forwarding rule, this AFT provides a flexible match criteria, and is indexed based on an arbitrary 64-bit index. Entries within the AFT may match on multiple field types (e.g., L4 header fields, as well as L2 fields). Examples of entries within this table are: - IPv4 policy-based routing based on DSCP. - MPLS policy-based forwarding entries
type:
