DMVPNs in R&S lab?

Hi Group,

I found a how-to from Petr describing how the DMVPNs are working and I was wondering if there is such topic in the lab because I didn't notice it in the blueprint.

  • It's mainly for the security lab because it's typically an IPsec feature. It's essentially an automatic full mesh of lan to lan IPsec VPNs.

    Thanks Brian. I got a strange task from a friend who had 4 routers in the broadcast domain and he had to configure OSPF between two of them without using the secondary address. I solve the case with GRE tunnel in between but according his SG this case should be solved with multipoint GRE + NHRP (dmvpn) ; I do know what NHRP does,however, if you you have just two routers I don't see a reason of multipoint gre + NHRP with multicast mappings.The only thing I can think of is if you are asked to simulate broadcast over NBMA network.

  • Technically DMVPN is not a V4 topic. But if you take a look at v4 extended blueprint I even can't find things like Bridging, L2 tunneling, SSM, IGMPv3 too. So we never know :-)
