    Configuring a Destination Profile for Dynamic GRE Tunnels

    To configure a destination profile for dynamic GRE tunnels:

    1. Configure a destination profile for GRE.

      host1(config-dest-profile)#gre destination profile kanata1 virtual-router vr1

    2. Set the source address for the tunnel.
      host1(config-dest-profile)#tunnel source 1.1.1.1
    3. Set the destination address for the tunnel.
      host1(config-dest-profile)#tunnel destination subnet 10.0.0.0 255.0.0.0
    4. (Optional) Set the maximum transmission unit (MTU) size for the tunnel.
      host1(config-dest-profile)#tunnel mtu 10240
    5. (Optional) Configure an IP profile with parameters that are used to stack an upper IP interface over a dynamic GRE tunnel.
      host1(config-dest-profile)#profile ip-kanata
    6. (Optional) Enable error checking across a GRE tunnel.
      host1(config-dest-profile)#tunnel checksum
    7. (Optional) Enable sequence number generation for a GRE tunnel.
      host1(config-dest-profile)#tunnel sequence-datagrams
    8. (Optional) Enable IPsec transport mode.
      host1(config-dest-profile)#enable ipsec-transport
    9. (Optional) Create a multicast VPN tunnel.
      host1(config-dest-profile)#tunnel mdt profile kanata-mdt
