Can my ASR 9000 upgrade to 4.3.4 to support MPLS?

[wang_dongmei888]

Hi All,

I have an ASR 9000, but it doesn't support MPLS. The current release is 4.2.1, and if is it possible for me to upgrade it to 4.3.4? When I login with my CCO account, I found the software is 4.3.4(MD), and why it has an MD?

Thanks,

Mei

Thank you Luis.

I will try it today, and if there are any problems I hope further support for you.

Keep in mind that the last day for 4.3.4 support is April 30, 2020 which is fast approaching. Considering you're on 4.2 I assuming that isn't a big problem for you now but it is still something to consider.
