Start Here: Cisco IOS Software Release Specifics for IPv6 Features This document lists the IP version 6 (IPv6) features supported in the 12.0S, 12.xT, 12.2S family, XE, 12.3, and 12.4 Cisco IOS software release trains. The IPv6 for Cisco IOS Software feature documentation provides implementation and command reference information for IPv6 features supported in the Cisco IOS software. This Start Here document details only the Cisco IOS software release specifics for IPv6 features. Not all IPv6 features may be supported in your Cisco IOS software release. We strongly recommend that you read this entire document before reading the other IPv6 for Cisco IOS software feature documentation. Finding Support Information for Platforms and Cisco IOS and Catalyst OS Software Images Use Cisco Feature Navigator to find information about platform support and Cisco IOS and Catalyst OS software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn. An account on Cisco.com is not required. The Cisco IOS IPv6 Configuration Library, which includes this document, is located at the following website: http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide The Cisco IOS IPv6 Command Reference is located at the following website: http://www.cisco.com/en/US/docs/ios/ipv6/command/reference The following sections are included in this document: • Cisco IOS Software Platform Dependencies and Restrictions, page 2 • Cisco IOS IPv6 Features and Supported Software Releases, page 2 • Cisco Platforms Supporting IPv6 Hardware Forwarding, page 20 • Additional References, page 23Start Here: Cisco IOS Software Release Specifics for IPv6 Features Cisco IOS Software Platform Dependencies and Restrictions IPv6C-2 Cisco IOS Software Platform Dependencies and Restrictions IPv6 features are supported in the 12.0S, 12.xT, 12.2S, 12.2SB, 12.2SE, 12.2SG, 12.2SR, 12.2SX, XE, 12.3, and 12.4 Cisco IOS software release trains, starting at Cisco IOS Release 12.0(22)S, 12.2(2)T, 12.2(14)S, 12.2(28)SB, 12.2(25)SEA, 12.2(33)SRA, 12.2(17a)SX1, Cisco IOS XE Release 2.1, 12.3, and 12.4, respectively. See Table 1 to determine which IPv6 features are supported in each release of the 12.0S, 12.xT, 12.2S, 12.2SB, 12.2SR, 12.2SX, Cisco IOS XE Release 2.1, 12.3, and 12.4 Cisco IOS software trains. • IPv6 was introduced on the 12.0(21)ST Cisco IOS software release train, which was merged with the 12.0S Cisco IOS software release train starting at Cisco IOS Release 12.0(22)S. The 12.0S Cisco IOS software release train provides IPv6 support on Cisco 12000 series Internet routers and Cisco 10720 Internet routers only. • The 12.2S Cisco IOS release train comprises a family of release trains, each supporting different platforms as follows: – The 12.2SB Cisco IOS release train comprises the Cisco 10000, 7304, 7301, and 7200 series. As of Cisco IOS Release 12.2(33)SB, the Cisco 7200 and 7301 series are not supported on the 12.2SB release train. – The 12.2SE Cisco IOS release train consists of the Cisco Catalyst 3560, 3750, 3560E, and 3750E series. – The 12.2SG Cisco IOS release train consists of the Cisco Catalyst 4500 and Cisco Catalyst 4900 series. – The 12.2SR Cisco IOS release train consists of the Cisco 7600 and 7200 series routers. In addition, Cisco IOS XE on ASR 1000 series routers inherits IPv6 features from 12.2SR releases but does not support all features on this train. – The 12.2SX Cisco IOS release train consists of the Cisco Catalyst 6500. Before the 12.2SR Cisco IOS release train, the 12.2SX release train also included the Cisco 7600 series. • IPv6 is also supported in some special software release trains. Cisco IOS IPv6 Features and Supported Software Releases Table 1 lists the IPv6 features supported in the 12.0S, 12.xT, 12.2S, 12.2SB, 12.2SR, 12.2SX, Cisco IOS XE Release 2.1, 12.3, and 12.4 Cisco IOS software release trains. Note Table 1 identifies the earliest release for each software release train in which the feature became available. Unless noted otherwise in Table 1, subsequent releases of that Cisco IOS software release train also support that feature.Start Here: Cisco IOS Software Release Specifics for IPv6 Features Cisco IOS

A ping in the fast-path mode is not supported. The support rate is limited to 10 pings per second per interface. 2. In Cisco IOS Release 12.0(23)S, the Cisco 12000 series Internet router provides enhanced performance for IPv6 manually configured tunnels by processing traffic on the line card. 3. The Cisco 10720 Internet router is supported in Cisco IOS Release 12.0(26)S. 4. IPv6 extended access control lists and IPv6 provider edge routers over MPLS are implemented with IPv6 hardware acceleration on the Cisco 12000 series Internet router IP service engine (ISE) line cards in Cisco IOS routers in Cisco IOS Release 12.0(25)S and later releases. 5. The RIP for IPv6 feature was updated in Cisco IOS Release 12.2(13)T. 6. Enhancements were made to several multiprotocol BGP commands. 7. SNMP versions 1, 2, and 3 are supported over an IPv6 transport. 8. In Cisco IOS Release 12.0(32)S, the Dynamic Host Configuration Protocol (DHCP) for IPv6 prefix delegation is supported on shared port adaptors (SPAs) in the 10G Engine 5 SPA Interface Processor (SIP) on the Cisco 12000 series Internet router only for stateless address assignment. 9. This feature may not be useful without either the IPv6 over PPPoE or IPv6 over PPPoA features, and the IPv6 over PPPoE or IPv6 over PPPoA features are not supported in Cisco IOS Release 12.2(28)SB. 10. Support for this feature is provided in Cisco IOS Release 12.2(33)SCA (see Table 3). 11. Feature is supported on Cisco 12000 series Internet routers in Cisco IOS Release 12.0(26)S. 12. IPv6 over IPv4 GRE tunnels are not supported on the Cisco 12000 series Internet router. 13. Feature is supported on the Cisco 12000 series Internet router only. 14. Only ATM PVCs are supported on the Cisco IOS 2.0S software release train. ATM LANE is not supported. 15. Frame Relay PVCs are not supported by distributed CEF switching for IPv6 in the 12.0S Cisco IOS software train. In the Cisco 12000 series Internet routers, Frame Relay encapsulated IPv6 packets are process switched on the Route Processor. 16. In 12.2(28)SB, PPPoA, PPPoE, and PPP over a VLAN are not supported. PPP over a serial link is supported.
