32-bit ASN for 7200 G2?

I'm researching IOS versions for upgrading our transit routers to
support 32-bit ASNs, and it seems that I need to use basically the
absolute latest 12.4T release (12.4.24T) to get that support. I can't
get it in 12.2S or 12.4 mainline at all.

Is that really the case?

What does everyone else use on their G2/7201s? This is just for BGP
internet peering connections and OSPF. Nothing at all fancy, I just
don't like the bleeding edge :-)

Thanks,

Howie

Hi,

You can wait a couple of weeks and get the feature on 12.2SRE.
32-bit ASN should be around on 12.0S images aswell.

Cheers,
Paolo

Yeah, the 12.4(24)T, rebuilds of it and the new 15.0M line. It will
also appear in the 12.2SRE.

If you're afraid of following the edge, 4-byte ASN support is also
present in the 12.0(33)S rebuilds.

And from 12.0(32)SY8 onwards, please refer to
