Adding a PGC to the VPG Configuration

To configure a PGC for a VPG, specify the IP address and port number of the PGC. You can also secure the connection by specifying an algorithm for the interim AH scheme.

Step-by-Step Procedure

To configure a PGC for a VPG:

  1. Access the configuration of the VPG for which you want to add a PGC
    [edit services pgcp]
    user@host#edit gateway vpg-1
  2. Create a PGC configuration, and assign a name to the PGC. You can configure an IP address as the PGC name. However, the IP address is not used for the connection to the PGC.
    [edit services pgcp gateway vpg-1]
    user@host#edit gateway-controller pgc-1
  3. Specify the IP address of the PGC.
    [edit services pgcp gateway vpg-1 gateway-controller pgc-1]
    user@host#set controller-address 10.10.2.3
  4. Configure the number of the PGC listening port. The VPG sends H.248 messages to this port.
    [edit services pgcp gateway vpg-1 gateway-controller pgc-1]
    user@host#set controller-port 2944
  5. To use the interim authentication header (AH) scheme to provide security on the PGCP connection, configure the security algorithm that the interim AH scheme uses. Currently, HMAC null is the only algorithm supported.
    [edit services pgcp gateway vpg-1 gateway-controller pgc-1]
    user@host#set interim-ah-scheme algorithm hmac-null
