[c-nsp] ip helper-address redundancy on Catalyst 6500?

[Murphy, William]

You could also go to a VSS distribution layer and eliminate HSRP, but that
involves shelling out mucho moula...

Hi,

> After years of abusing our DHCP servers with both the active & standby
HSRP routers forwarding DHCP requests, today I stumbled across information
about "UDP Forwarding Support of IP Redundancy Virtual Router Group" [1].
Having only the active router forward DHCP requests sounds fantastic.  So I
went onto our test Catalyst 6500 and tried to configure "ip helper address
<XXX.XXX.XXX.XXX> redundancy <vrg-name>", but the redundancy keyword is not
recognized.  We're running 12.2(33)SXH7 on our 6500s.  According to the doc
support for this feature was added in 12.2(15)T, but I don't know if/how
that translates to the SX train.  Does anyone have this working on a 6500?
If so, what software version?  Or if it's not currently supported on the
6500s, has anyone heard if it will be coming to the 6500s?  While I'm at it,
does anyone know if the Nexus 7000 has a feature similar to this?

in this case 12.2(15)T doesnt map at all to any 65k SX(F|H|I) releases.  it
does sound intriguing though - count me in as +1 for wanting to see this
feature in SXI at least :-)
