ISIS Leaked Route Summarization is a feature which summarizes all the L1 leaked routes in L2 routers. With the help of this L2 LSP size reduces (smaller no of routes in L2 LSP). 

This feature allows routes that were leaked from one VRF (the source VRF) into another VRF (the destination VRF) using

When there are multiple VRFs on the device and there is a need to share routes between them, typically for shared

VRF Route leaking can be used when routes from one VRF are required in another VRF (e.g. in case of shared services). If VrfLeak Agent is being used to leak routes, the leaked routes (in destination VRF) can be redistributed into IGPs.

Routing control functions (RCF) is a language that can be used to express route filtering and attribute modification logic in a powerful and programmatic fashion. This document serves as a reference guide for Bgp agent points of application:

Currently EOS supports redistribution into BGP at the global ( instance ) level. Also EOS supports redistribution in BGP at Address Family Identifier/Subsequent Address Family Identifier(AFI/SAFI) level to some extent. But the current redistribution mechanism is not flexible and does not provide full control at AFI/SAFI level ( some redistribution protocols are only supported at global level, or at some AFI/SAFI level ). This feature will support redistribution at AFI/SAFI level as well as at the global level. This will simplify the configuration requirements and supportability for complex and granular configurations when subsequent address family configurations co-exist. This will also give more control at AFI/SAFI level ( for example, route-map/rcf can be configured at AFI/SAFI level while they are not configured at global level ). This feature only works in multi-agent routing model.

EOS 4.23.0F adds support for redistributing DHCPv6 routes in IS IS when using the multi agent routing protocol mode.

EOS 4.23.0F adds support for ‘match ip next hop’ clause for static routes redistributed into IGPs.
