Which HA design do you prefer ?

[salemmahara]

Hello everybody

According to attached picture:

1. Which design is your preferred ? Why?

2. What is deference between NHRP and Interchassis HA? I know ASR 1000 series support Interchassis HA and NHRP both. But ISR series probably don't support that so the only available option would be NHRP. Right?

3. Any other option available to implement edge redundancy ?

Is there any way in these scenarios to minimize configuration? Imagine you want to implement NAT or ACLs or .... . You have to do the same thing on both router. Right or ... ?

BTW, do you prefer ASR 1000 over ISR 4000? Why? If you were going to buy a pair of router for your edge to interconnect with your branches in WAN including IPsec and DMVPN and also Dynamic routing and NAT with some other routers in you MAN, which platform did you choose? ISR or ASR?

Personally if your organisation looking more resilience from your PDF Option5. with some tweaking setup.

Cisco have some good CVDs.

NHRP and Interchassis HA - Both are different topics.

ASR or ISR again a depends on organisation budget and feature support your looking.

Thank you Balaji

If you had both NHRP and Interchassis as an option, Which one did you go for?
