Redundancy and load sharing on more than 2 CSS's

[ct_yau]

Hello,

I have configured VIP, virtual interface and ASR on a pair of CSS's before. Currently, I have some VIP on CSS1 and some other VIP on CSS2 for resilience.

Because of performance issue (actually a fear for performance issue instead of real) I am looking into scaling up to 3 or more CSS's. I think I can have VIP and virtual interface redundancy on 3 or more CSS's but not ASR. Is it true?

Any advice will be welcomed.

normally vip redundancy and asr are for pair of css only.

I think you can do vip redundancy with more than 2 CSS but it is officially not supported.

You can however have multiple VRRP group per interface and therefore combine your CSS by pair [a-b,b-c,a-c]

ASR is definitely not going to work with more than 2 CSS.
