Hi,
I'm building a design for a LAN and was thinking of using nexus 93xx as my core switch (x2) and 3850s as my access switches. I'd like to ask on the nexus switch how or what do you configure on to have HA on vlan interfaces (svi).
From the data sheets is has
490 Maximum number of Hot-Standby Router Protocol (HSRP) groups
Is it still HSRP?
Any help or link would be appreciated.
Thank you,

Only the other standard FHRPs but your limited on 9Ks they don't support GLBP only VRRP & HSRP as its a stripped down version of NX-OS , no bgp/mpls/rspan/ vdc etc 9ks still missing a bit , great hardware though

Yes you can still use HSRP , its just set slightly different , for faster failover in DC environments BFD is usually used with it as it reduces failover times
standard port-channel on 3850 side and just a vpc port-channel on 9k side so its split across both
example of one of my 7ks lab switches using bfd we dropped failover times from 14 seconds to 1 by using bfd with hsrp , but you can just use hsrp on its own , I think hsrpv2 will support more groups than that 4096 if used

Thank you for the prompt reply Mark! Do you know any other HA option apart from HSRPv2+BFD?
