LACP as L3 interface on M4300 series
Hi, We have a couple of M4300-96X which are used as the primary switches for our storage network. Currently the storage network is linked to the rest through a L2 LACP LAG. As on ongoing redesig...
LACP LAG is always a L0...L2 feature. The question is if the L3 routing does support the LAG interfaces - what I think it does. LaurentMa please.
true, but you understand what I mean...
Trying is knowing...
(Interface lag 3)#routing
An invalid interface has been used for this function.
A valid routing interface must be specified.
lag 3
Routing cannot be enabled on this type of interface
:smileysad: that's a bummer...
Any ideas on how we could accomplish more or less the same without routing on the lag?
equal path routing on the interfaces themself without putting them in a lag?
- Hi swbelgium
Thank you for your message and please excuse the brievety of my response on the road here. I think you should achieve your goal by enabling L3 routing on a VLAN IP interface instead of a physical LAG interface. This should be the standard as LAG are meant to be trunks carrying multiple VLANs.
I hope it can help
RegardsHi Laurent,
no problem.
well, that could work if and only if we could somehow make the vlan interface go down if the LACP interface is down.
Otherwise the route would remain up even if the next-hop on the other side of the LAG is unreachable (or am I missing something?).r,
Sam
