Hi All,
The scenario is a DMVPN hub and spoke topology running EIGRP between the hub and spoke sites.We are trying to adjust the NHRP holdtime in accordance with EIGRP.We had set NHRP holdtime to 360 seconds.If the serial link goes down,the tunnel interface doesnt come up for 360 seconds and we dont want that.Is there an optimal NHRP holdtime value to setup with EIGRP convergence?
