Creating a Destination Profile for DVMRP Tunnels

To configure a destination profile for dynamic DVMRP tunnels:

1. Configure a destination profile for DVMRP.

   host1(config-dest-profile)#dvmrp 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 DVMRP tunnel.

   host1(config-dest-profile)#profile ip-kanata

6. (Optional) Enable IPSec transport mode.

   host1(config-dest-profile)#enable ipsec-transport

7. (Optional) Create a multicast VPN tunnel.

   host1(config-dest-profile)#tunnel mdt profile kanata-mdt

dvmrp destination profile

• Use to configure a destination profile for dynamic DVMRP tunnels.
• Use the any-virtual-router keyword to create a default destination profile for all virtual routers. There can only be one default destination profile defined in the system.
• Use the virtual-router keyword to specify a specific transport virtual router.
• Example

  host1(config)#dvmrp destination profile kanata1

• Use the no version to delete the destination profile.
• See dvmrp destination profile.

enable ipsec-transport

• Use to specify that the router accepts only dynamic IP tunnels protected by an IPSec transport connection.
• This command is supported in the destination profile only when you have installed an ISM on ERX routers.
• Example

  host1(config-dest-profile)#enable ipsec-transport

• Use the no version to disable IPSec transport mode.
• See enable ipsec-transport.

gre destination profile

• Use to configure a destination profile for dynamic GRE tunnels.
• Use the any-virtual-router keyword to create a default destination profile for all virtual routers. There can only be one default destination profile defined in the system.
• Use the virtual-router keyword to specify a specific transport virtual router.
• Example

  host1(config)#gre destination profile kanata2

• Use the no version to delete the destination profile.
• See gre destination profile.

profile

• Use to assign an IP profile with parameters that are used to stack an upper IP interface over a dynamic GRE or DVMRP tunnel to the destination profile.
• Example

  host1(config-dest-profile)#profile ip-kanata

• Use the no version to remove the profile assignment from the destination profile.
• See profile.

tunnel checksum

• Use to enable checksum computation across a GRE tunnel.
• Checksum computation is not supported for DVMRP tunnels.
• Selecting this feature causes the E-series router to drop corrupted packets it receives on the tunnel interface.
• Example

  host1(config-dest-profile)#tunnel checksum

• Use the no version to disable the checksum option.
• See tunnel checksum.

tunnel destination

• Use to configure the remote end of the tunnel.
• Specify the IP address of an interface on the remote router or the range of destination addresses:
  • Use the subnet keyword to configure the IP address for the destination interface and the mask.
  • Use the range keyword to configure the first IP address and the last IP address of the destination interface range
• Example 1—Specifies an IP address and mask for the destination interface

  host1(config-dest-profile)#tunnel destination subnet 192.13.7.1 255.0.0.0

• Example 2—Specifies a range of IP addresses for the destination interface

  host1(config-dest-profile)#tunnel destination range 192.13.7.1 192.13.7.20

• Use the no version to remove the destination of a tunnel.
• See tunnel destination.

tunnel mdt profile

• Use to enable multicast distribution tree operation so the IP tunnel component can create an MDT interface.
• The command defines an IP profile with parameters that are used to stack an upper IP interface over a dynamic GRE or DVMRP tunnel.
• Example

  host1(config-dest-profile)#tunnel mdt profile kanata-mdt

• Use the no version to disable MDT on the interface.
• See tunnel mdt profile.

tunnel sequence-datagrams

• Use to enable GRE sequence numbers.
• Specify GRE sequence numbers at both ends of the GRE tunnel.
• Example

  host1(config-dest-profile)#tunnel sequence-datagrams

• Use the no version to disable sequence numbers.
• See tunnel sequence-datagrams.

tunnel source

• Use to configure the source of the tunnel.
• Specify either the primary IP address or the type and specifier of an interface. Do not specify an unnumbered interface.
• You can configure multiple sources in a GRE destination profile or a DVMRP destination profile.
• Example

  host1(config-dest-profile)#tunnel source 11.11.11.11

• Use the no version to remove the source of a tunnel.
• See tunnel source.
