I was just talking about Cisco. There is not concept that prevents a PE router from doing nat. -----Original Message----- From: Andrew Walker To: Javier Antich Cc: Robert Staats; 'alfred zhang'; mpls-ops@mplsrc.com Sent: 20/09/01 15:37 Subject: RE: nat at the PE I respectfully disagree. It IS possible to do NAT at the PE (just not with cisco or juniper equipment). Many carriers are beginning to do just that with CoSine equipment. The IPSX can perform NAT on a per-VRF in the network (without burdening the CE and without external NAT equipment)!
