Hello,
I am doing some lab these days on DMVPN as i am preparing the RS v5 lab.
I got this issu with GNS3 7200 router and latest IOS image c7200-adventerprisek9-mz.152-4.S5.bin.
When I try to configure DMVPN phase 3, I can not enable the nhrp redirect feature on the hub :
R1(config-if)#ip nhrp redirect
% NHRP-WARNING: 'ip nhrp redirect' failed to initialise
DMVPN phase 1 and 2 work fine with the same configuration.
Does anyone here already got this error message and found a solution?
