I&#39;m asking because I&#39;m trying to deploy it on dynamips and I&#39;m stuck atm with 3640 routersVlaadnoreply@blogger.comtag:blogger.com,1999:blog-23021255.post-75571149815552948172010-03-18T16:53:00.000+01:002010-03-18T16:53:00.000+01:00This seems to be an OR poll.. The previous provider I worked at did 2 of the options and the third was considered in one of the Sub-AS. <br /><br />6PE w MPLS on P Nodes &amp; Natively w BGP on P node. 6VPE considered but not sure of outcome.<br /><br />V4 is the same which the v6 topology followed.. In fact, in my experience (And I am pure Core guy ie. no dns/nat/cpes) deploying IPv6 was as easy as another address family.<br /><br />In mobile operators I have only seen Internet in VPN and am yet to see v6 just massive NAT boxes (which imo is bottleneck)<br /><br />In the end the decision must come down to whether you already have a BGP Free Core or not.<br /><br />As a corollary,there is an argument that we buy all the super powered CRS/T1600 etc and then remove BGP from the core. In reality if they are so super (and expensive) there surely adding BGP to the core should be a walk in the park for these big boys ;-)Bad Designernoreply@blogger.comtag:blogger.com,1999:blog-23021255.post-35881862319769973902010-03-18T14:28:24.000+01:002010-03-18T14:28:24.000+01:00Ivan<br />I am working on the design where in pitching MPLS as core for serving IPv6 internet. This will help SP not to add any IGP for IPv6 traffic. <br />I have added a HLD for the same on blog http://www.mplsvpn.info/2010/03/ipv6-internet-in-vrf-over-mpls.html<br /><br />Challenges:-<br />1. The first challenge is the DNS. In that case we need to use the two interface on DNS one for forwarding and another for reverse. <br />2. Proxy.<br /><br />I am also working on the solutions. Will come up with new updates :)shivlu jainnoreply@blogger.comtag:blogger.com,1999:blog-23021255.post-10829952409617306142010-03-17T19:16:13.000+01:002010-03-17T19:16:13.000+01:00You&#39;re absolutely correct. MPLS is still single-protocol O:-) There is no LDPv6; it also doesn&#39;t work with MPLS TE. The only way to make use of MPLS is to use 6PE (as visir indicated).Ivan Pepelnjaknoreply@blogger.comtag:blogger.com,1999:blog-23021255.post-68182321822305685232010-03-17T18:29:48.000+01:002010-03-17T18:29:48.000+01:00Don&#39;t forget about 6PE - IPv6 routes distributed via BGP with label explicit-null, with this you don&#39;t need IPv6 support in the core at all.visirnoreply@blogger.comtag:blogger.com,1999:blog-23021255.post-77000594357531914592010-03-17T15:30:42.000+01:002010-03-17T15:30:42.000+01:00Hi Ivan,<br /><br />correct me if I am wrong, but there is no LDPv6, hence no IPv6 in the core.....jumbonoreply@blogger.com
