Having worked for seveal SP's 'tier 1' and otherwise along with a couple of router vendors IMO MT is one of those thing people ask for just in case. Sure we _could_ always find a use for it, but we don't always look at the potential diffrent IGP topologies are going to cause for our NOC staff @ 2am over a holiday weekend when some does decide to break. -jim ------Original Message------ From: Randy Bush To: Mark Tinka Cc: nanog@nanog.org Subject: Re: IPv6: IS-IS or OSPFv3 Sent: Dec 27, 2008 9:27 AM
For IS-IS, highly recommend MT to avoid any nasties while turning up v6 in a dual-stack environment.
as one who has been burned when topologies are not congruent, i gotta ask. if i do not anticipate v4 and v6 having different topologies, and all my devices are dual-capable, would you still recommend mt for other than future-proofing? randy Sent from my BlackBerry device on the Rogers Wireless Network
