match is made or the route is processed by all entries in the route map with no match. If the router
processes the route against all entries in a route map with no match, the router accepts the route (inbound
route maps) or forwards the route (outbound route maps).
Note When you redistribute BGP to IGP, iBGP is redistributed as well. To override this behavior, you must
insert an additional deny statement into the route map.

Policy-Based Routing

You can use policy-based routing to forward a packet to a specified next-hop address based on the source
of the packet or other fields in the packet header. For more information, see
Policy-Based Routing."

If you configure VDCs, install the Advanced Services license and enter the desired VDC (see the
Cisco NX-OS Virtual Device Context Configuration Guide).
An empty route map denies all the routes.
An empty prefix list permits all the routes.
Without any match statement in a route-map entry, the permission (permit or deny) of the route-map
entry decides the result for all the routes or packets.
If referred policies (for example, prefix lists) within a match statement of a route-map entry return
either a no-match or a deny-match, Cisco NX-OS fails the match statement and processes the next
route-map entry.
When you change a route map, Cisco NX-OS hold all the changes until you exit from the route- map
configuration submode. Cisco NX-OS then sends all the changes to the protocol clients to take
effect.
