RT is a control plane parameter and not data plane therefor you can use it to control what goes in or our of your VRF table. It has nothing to do with applying any policy to the particular sources in your VPNs. For this you should be applying regular ACL on the appropriate vrf's interface.

I am not responsing to your question due to travelling but I think you can match today with not full reg exp but at least wild cards in the route map RT match statament. When I double check with running IOS I will confirm, R. > Kim Quang Vo wrote: > > I have the same question : > May I use RT filter for limit one member of VPN. > That means source 10.1.1.0/24 has only permit to 10.1.250.0/24 but not > others in the VPN . > > Kim > > ----- Original Message ----- > From: "Marcelo Blanes" <mblanes@larc.usp.br> > To: "Robert Raszuk" <raszuk@cisco.com> > Cc: <mpls-ops@mplsrc.com> > Sent: Sunday, August 26, 2001 1:55 AM > Subject: Re: RT filtering > > Robert, > > What I would like to do is use regular expression like: > > ip extcommunity-list expanded NAME permit <regular expression> > > I think IOS does not support it for now.
