MPLS VPN Export Without MPLS labels

Description RFC4364 supports exporting VRF routes into the VPN table and advertising these VPN routes to peers. Exporting the VRF IPv4/IPv6 Unicast routes as MPLS VPN routes requires MPLS labels to be allocated for each route. MPLS label allocation is supported only on some platforms. On other platforms, where MPLS label allocation is not supported, VRF routes can still be exported as VPN routes without having to allocate MPLS labels, with the support of this feature. These routes are exported with dummy labels ( explicit-null MPLS label ) if this feature is enabled. Platform compatibility This feature is supported on...

Prefix-length support for IPv6 attached-host routes

Description This feature supports generation of non-host routes for the IPv6 neighbor entries learnt on an SVI interface. These non-host routes can further be redistributed into BGP protocol to take part in the route selection decision process and to get advertised to the peers. These routes are not installed into the hardware and are only being generated for advertisement purpose. This feature works for both static and dynamic neighbors. Neighbor generated routes are also referred to as ‘attached-host’ routes in the context of this document even though the routes are non necessarily host routes ( /128 ). A neighbor will...

IPv6 and VRF support for ARP converted Host routes injection into BGP

Description This features enables neighbors learnt on an SVI interface to be converted into IPv6 Host routes which can further be redistributed into BGP protocol to take part in the route selection decision process and to get advertised to the peers. These Host routes are not installed into the hardware and are only being generated for advertisement purpose. This feature works for both static and dynamic neighbors. A neighbor will be converted to Host route, if the feature is enabled using the CLI (as described in the ‘Configuration’ section), and corresponding MAC address exists in the MAC table Host route...

ARP converted Host Routes injection into BGP

This features enables ARPs learnt on an SVI interface to be converted into Host routes which can further be redistributed into BGP protocol to take part in the route selection decision process and to get advertised to the peers. These Host routes are not installed into the hardware and are only being generated for advertisement purpose. This feature works for both static and dynamic ARPs. ARP will be converted to Host route, if the feature is enabled using the CLI (as described in the next section), and corresponding MAC address exists in the MAC table Host route will be deleted,...
