Cisco 4431 High Availability between two WAN or MPLS links

Hi All

 

I got a question about the cisco 4431, is it possible for this device to handle a High Availability (active-stanby) configuration between two WAN or MPLS links? I'm a little confuse if the device needs the VIPTELA or DNA license or it doesn't need any special license.

 

Also i'm a noob in VIPTELA or DNA fields so that why i'm asking.

 

Thanks

Re: Cisco 4431 High Availability between two WAN or MPLS links

Hi,

High Availability means, Are you looking only WAN to WAN or MPLS to MPLS on a single chassis or both are connected on the different Chassis?

If both are on the same chassis then you can go with IPSLA and tracks with floating routing. If both are on the different chassis then many options (protocols) are there and you can go with Inter-Chassis High Availability

My scenario is MPLS to MPLS on the same chassis.

Also i'm looking at this documentation https://www.cisco.com/c/en/us/td/docs/routers/access/4400/software/configuration/xe-16-9/isr4400swcfg-xe-16-9-book/configuring_high_availability.pdf but it for the HA scenario when you have two devices. 

 

I guess my option will be the IPSLA or tracking for the interfaces right? Do you have any documentation for that because I cannot find it.

 

Regards.
