H.248 Configurable VRF

In the previous release, only the default VRF could be used for setting up an H.248 association. The DBE now allows using other VRF names. This enhancement enables the DBE to use VRF names for configuring the control addresses and remote addresses.

Information About H.248 Configurable VRF

The DBE communicates with the Media Gateway Controller (MGC) over the H.248 protocol. In the past, this MGC had to belong to the global IP address space. The new feature allows you to use the MGC controller signaling address with specific VRF names instead of the default VRF name, and, thereby, enables the MGC controller address to use the VPN functionality.

How to Configure H.248 VRF

This section contains the steps for configuring H.248 configurable VRF.

Configuring H.248 Configurable VRF

SUMMARY STEPS

1. configure

2. sbc service-name

3. dbe

4. vdbe [global]

5. control-address h248 ipv4 ipv4_address

6. controller h248 controller-index [vrf vrf_name]

7. remote-address ipv4 ipv4_address

8. commit

9. exit

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

configure

Example:

RP/0/0/CPU0:router# configure

Enables the global configuration mode.

Step 2 

sbc service-name

Example:

RP/0/0/CPU0:router(config)# sbc mysbc

Enters the mode of an SBC service.

Use the service-name argument to define the name of the SBC.

Step 3 

dbe

Example:

RP/0/0/CPU0:router(config-sbc)# dbe

Enters the mode of the data border element (DBE) function of the SBC.

Step 4 

vdbe [global]

Example:

RP/0/0/CPU0:router(config-sbc-dbe)# vdbe

Enters the mode for configuring virtual DBE (vDBE) parameters.

Step 5 

control-address h248 ipv4 ipv4_address

Example:

RP/0/0/CPU0:router(config-sbc-dbe-vdbe)# control-address h248 ipv4 10.2.0.10

Configures the control address for vDBE with a specific VRF name.

The no version of this command cancels this configuration option.

•ipv4_address—IPv4 address assigned to this H.248 association.

Step 6 

controller h248 controller-index [vrf vrf_name]

Example:

RP/0/0/CPU0:router(config-sbc-dbe-vdbe)# controller h248 1 vrf vrf1

Configures the index and VRF name for the vDBE H.248 controller.

The no version of this command cancels this configuration option.

•controller-index—Index of the media controller. Values are 1-4294967295. This value is mandatory. There is no default.

•vrf_name—Name of the specific virtual private network chosen for the remote address for vDBE H.248 controller.

Step 7 

remote-address ipv4 ipv4_address

Example:

RP/0/0/CPU0:router(config-sbc-dbe-h248)# remote-address ipv4 34.34.34.34

Configures the remote address for vDBE H.248 controller.

•ipv4_address—IPv4 address assigned to this H.248 association.

Step 8 

commit

Example:

RP/0/0/CPU0:router(config-sbc-dbe-h248)# commit

Saves configuration changes. Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.

Step 9 

exit

Example:

RP/0/0/CPU0:router(config-sbc-dbe-h248)# exit

Exits the current mode of the configuration.

Configuring H.248 VRF: Example 

The following example shows how to configure H.248 VRF:

config

sbc siptest

 dbe

  vdbe

   control-address h248 ipv4 10.2.0.10

   controller h248 1

    vrf vrf1

    remote-address ipv4 34.34.34.34
