In BGP this is the very basic/fundamental concept involved in withdraw: When sending a withdraw message you dont send all the path attributes that you had advertised along with the prefix before. All you have to do is send the prefix as unfeasible. The short answer for your question is: i. understand the messaging process for "withdraw" in BGP. ii. read & understand the MP-UNREACH message. - pamsri Rajesh wrote: -------- Original Message -------- Subject: BGP - 2547 VPNS Date: Fri, 15 Nov 2002 06:57:11 -0800 (PST) From: Rajesh Potti <rpotti123@yahoo.com> To: mpls@UU.NET Hi, In BGP for 2547 VPNs, can a VPN-IPv4 route be send with a set of route targets and then a withdraw with only a subset of the route targets. This will be a partial withdraw. How does a router handle a partial withdraw? If the route is removed from only the vpns in which there is an import Route target match, future updates for the route with a set of route targets will result in inconsistencies.
