Cisco Cisco IOS Software Release 12.2(33)SRE

© 2003–2007 Cisco Systems, Inc. All rights reserved.

The MPLS VPN—Route Target Rewrite feature allows the replacement of route targets on incoming and 
outgoing Border Gateway Protocol (BGP) updates. Typically, Autonomous System Border Routers 
(ASBRs) perform the replacement of route targets at autonomous system boundaries. Route Reflectors 
(RRs) and provider edge (PE) routers can also perform route target replacement.

The main advantage of the MPLS VPN - Route Target Rewrite feature is that it keeps the administration 
of routing policy local to the autonomous system.
