IPv6 HSRP

mrblackmamba343

IPv6 doesnt allow me to configure a global unicast address a HSRP virtual address? Or I'm not enabling something

Router1(config-subif)#standby 1 ipv6 ?
X:X:X:X::X IPv6 link-local address
autoconfig Obtain address using autoconfiguration

This should help you out if you haven't looked over it already.

Cisco IOS IPv6 Configuration Guide, Release 12.4T - Configuring First Hop Redundancy Protocols in IPv6 [Cisco IOS Software Releases 12.4 T] - Cisco Systems

I have already read that....

and based on the IOS I'm running it should be supported.

I don't think IPv6 HSRP supports global unicast addresses.

The following example shows three HSRP global IPv6 addresses with an explicitly configured link-local address:

interface Ethernet0/0

no ip address

ipv6 address 2001::DB8:1/64

standby version 2

standby 1 ipv6 FE80::1:CAFÉ

standby 1 ipv6 2001::DB8:2/64

standby 1 ipv6 2001:DB8::3/64

standby 1 ipv6 2001:DB8::4/64

end

end

HSRPv6 supports global-unicast addressing, but per the OPs IOS release documentation it is not supported.

which means it is currently not supported?

QHalo

Feature Navigator seems to say it is supported. Use the navigator and then plug in the IOS you stated.

http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

Search by image and put this in - asr1000rp1-adventerprisek9.03.04.00.S.151-3.S.bin

It shows that HSRP for IPv6 is supported and then leads you to documentation on how to configure it for that IOS version.

This documentation has been moved - Implementing First Hop Redundancy Protocols in IPv6* [Support] - Cisco Systems

This link is different than the one I posted earlier, as the IOS is IOS XE and not IOS.
