SR520 DMVPN functionality problem

[vladimirtegeltija]

Hello people,

I have a serious problem with cisco SR 520 router and functionality that is wrote on the paper!

On cisco site I found that SR 520 support DMVPN, I ordered the router and it came with IOS:

(SR520-ADVIPSERVICESK9-M), Version 12.4(20)T6. Later I found that it does not support

NHRP protocol which is a base for DMVPN functionality and spoke-to-spoke VPN tunnels.

I suppose that the problem is in IOS version that is shiped with router.

Please, if you know, tell me were is the problem and wich IOS version should I choose ?

Should I take the latest ( 12.4.24T6) or some special release ?

Thanks in advance,

Vladimir

Hi Vladimir

DMVPN support on SR520 was indeed only added in 12.4(24)T so I would suggest to go for the latest, i.e. 12.4(24)T6.
