If it does, that's bad... You should never see IPv4 mapped addresses on the wire. They should only be an internal representation of an IPv4 packet within the host. Owen On Jun 15, 2012, at 3:52 AM, Nagendra Kumar (naikumar) wrote:
Hi, Per my understanding, it is not required to have ipv6 address in loopback intf on all P routers inorder to have 6PE work. If I remember it correctly, P router will use ::FFFF::<ipv4-addr> while originating ICMPv6 error message. -Nagendra -----Original Message----- From: Daniel Roesen [mailto:dr () cluenet de] Sent: Friday, June 15, 2012 4:02 PM To: nanog () nanog org Subject: Re: IPv6 Lo. for 6PE/6VPE On Fri, Jun 15, 2012 at 11:56:05AM +0200, mohamed Osama Saad Abo sree wrote:I was just wondering , while I'm planning my network to support 6PE/6VPE why should i assign an IPv6 for Loopbacks? Maybe it's needed for Point-Point links or external interfaces between my peers, but anyone here know why i should assign IPv6 for all my Routers inside my ISP if we will run PE/6VPE not dual stack.Otherwise the intermediate P devices do not have an address to source ICMPv6 "hop count exceeded" error replies => traceroute doesn't work properly.
