cisco 2851 Fast Track support

[tanios191]

Dear Team,

I have a router CME 2851 having the image below: 

c2800nm-adventerprisek9-mz.151-4.M8.bin

but I cannot apply the fast track configuration on this as the fast track configuration works with 15.3 and higher

and the latest image for it on cisco website is below:

151-4.M12a.bin

please advise if it is supported or unsupported

It's not supported as the 28xx cannot use 15.3, you need to replace your ISR with one that does support 15.3

[Jonathan Schulenberg]

Unsupported. That platform has been end of life for years.
