Comparing promises, deliverables and generic progress seems to be popular in the harvest season, so let’s see how far Cisco pushed the Data Center IPv6 support in the six months since my last status report.
Kudos to the Nexus 7000/NX-OS team for doing the right thing. Not only did they make me happy by implementing full-blown MPLS, MPLS/TE and MPLS/VPN, they included 6PE and 6VPE in the first release of the MPLS code. Great job!
ACE team managed to beat me to the punch and released A5(1.0) software with full IPv6 support literally hours before I published this post. Congratulations!
Honorable mentions to the security folks who managed to repackage ASA into a different form factor (good bye, FWSM) and IOS XE engineers who rolled out non-redundant stateful NAT 64 in IOS XE release 3.4S almost two years after it was announced.
Last but definitely not least, I will not comment on IronPort’s glacial release strategy. The last Cisco IronPort AsyncOS for Email was released a year ago; IPv6 support is supposedly roadmapped for second half of 2011.
And here’s the color-coded chart:
|Functionality||IPv6 readiness state|
|Routers||All WAN edge routers are IPv6 ready|
|Switches||Catalyst 6500, Nexus 7000|
|Nexus 5000 (no IPv6 routing), Nexus 1000V (no IPv6 PACL)|
|Servers||UCS infrastructure management (UCS Manager, KVM) works only over IPv4.|
|Firewalls||ASA and ASA Service Module for Catalyst 6500|
|Virtual Security Gateway filters IPv6 based on Ethertype|
|Email/Web security||IPv6 only supported by cloud-based Ironport solution (NAT64 anyone?)|
|Load balancers||SLB64, SLB46, NAT64, NAT46 available on ACE30|
|NAT64||Stateless and stateful NAT64 on ASR1000. Still waiting for stateful failover implementation.|
|WAN optimization||IPv6 not supported|
2011-09-21 07:50GMT - added Servers section and updated Load balancers section.
Getting more information
The problems you might encounter when deploying IPv6 in your data center are described in my Enterprise IPv6 – the first steps webinar (recording); a Service Provider-focused version is scheduled for October 19th (register). Both webinars are available as part of the yearly subscription.
