I would like to know what is configured on the DMVPN router connected to R1, R2, R3, R4, R5?

HI

R1, R2, R3, R4, R5 are connected to the DMVPN cloud and they do reside on the same subnet.

R1
interface GigabitEthernet1.100
encapsulation dot1q 100
ip address 169.254.100.1 255.255.255.0

R2
interface GigabitEthernet1.100
encapsulation dot1q 100
ip address 169.254.100.2 255.255.255.0 etc

I would like to know what is configured on the DMVPN router connected to R1, R2, R3, R4, R5?

Please advice

    not sure u asking for but dmvpn is vpn tunnel like gre tunnels. just start learning gre before moving to dmvpn. we can set up a tunnel over any ip network, even internet.

    underlay for tunnel is 169.254.100.x , dmvpn - call overlay - will run over it, source for dmvpn is interface GigabitEthernet1.100,
    to have any idea about how this works , look at initial configs for a lab where dmvpn is already set up; maybe bgp lab config have dmvpn already ready

  • Hi

    There is no ping between the routers. For ex R1 cannot ping R2 etc.

    Please advice

    What IP ping fails? What lab is loaded? What is lab setup?

    Load basic IP config lab with only IP initial configuration.
    You shouldn't have any tunnel config.
    Ping that 169 .x.x.x IP address from r1 to r5. If ping fails that is your lab set up at fault.
    Check CDP on routers, they should see only switch. Check that connected switch. Make sure it does trunking on interfaces and have vlans in database.

    If u have tunnel down or miss configured , ping 169.x.x.x may also fail because of tunnel down. U must fix tunnel.

  • Hi

    There are three folders which foundation initital labs. For ex foundation lab1 intial configuration, oundation lab2 intial configuration, oundation lab3 intial configuration.

    Which foundation lab should I use?

    Thanks

  • I was talking about main advanced technology labs. Foundation is one u have to build from almost nothing.

    Anyway, Load foundation 1 inital config.
    Check if u have tunnel configured or not.

    If u have no tunnel, Ping that 169 .x.x.x IP address from r1 to r5. If ping fails that is your lab set up at fault.
    Check CDP on routers, they should see only switch. Check that connected switch. Make sure it does trunking on interfaces and have vlans in database.

    In case of tunnel Config already there:
    If u have tunnel down or miss configured , ping 169.x.x.x may also fail because of tunnel down. U must fix tunnel.

  • OK, will start with that. Many thanks for your help

  • Np, good luck and have fun labbing
