Core group bridge settings

The core group bridge is the service that enables communication between core groups. A core group is a statically defined component of the high availability manager. To view the structure of the access point groups and tunnel access point groups.

Servers > Core Groups > Core group bridge settings.

An access point group links core groups in the same cell or in different cells. The access points defined for an access point group enable these core groups to communicate with each other. If one or more of the core groups reside outside of a firewall, also define a tunnel access point group, and at least one tunnel access point for each core group residings outside of the firewall.

Each access point group is a collection of core group access points. Each tunnel access point group is a collection of core group access points, and tunnel peer access points.

• If configuring communication between core groups in the same cell, configure an access point group with a core group access point for each core group in the cell.

• If configuring communication between core groups in different cells, configure an access point group that has one core group access point for the local cell and a peer access point for each other cell.

• If configuring communication between core groups, and one or more of the core groups reside outside of a firewall, configure a tunnel access point group with a core group access point for each core group residings inside of the firewall, and a tunnel peer access point for each core group residings outside of the firewall.

Each core group access point has one or more bridge interfaces. Each peer access point and tunnel peer access point has a proxy peer or one or more peer ports. A bridge interface is a server configured to communicate with other core groups by using a particular transport chain.

• Click Access point groups to configure the settings for each access point group configured.

• Click Tunnel access point groups to configure the settings for each tunnel access point group configured.

• Click Tunnel peer access points to configure the tunnel peer access points for a tunnel access point group.

• Click Tunnel templates to use one of the tunnel templates that are provided with WAS ND, to define a tunnel access point group and the tunnel access points for that group.

• Access point group - An access point group defines the core groups that need to communicate with each other. Each access point group consists of a collection of core groups.

  • Core group - Specifies a core group that is in this access point group. Core groups are referenced by core group access points.

    • Core group access point - The core group access point defines the set of servers that provide access to the core group. Bridge interfaces define the servers in the core group access point.

      • Bridge interface - A bridge interface defines a node, server, and chain for the core group access point. The chain defines the transport channels that the server uses for receiving information. Typically, all the bridge interfaces in a core group access point use the same chain.

        Avoid trouble: The bridge interfaces listed in the display tree on this page are listed as *,port. The asterisk symbol represents the multi-home support for DCS instead of a specific hostname.

  • Peer core group - Specifies a core group in a different cell. Define peer access points to communicate with peer core groups.

    • Peer access point - Each peer access point is used to establish communication with another core group. Each peer access point corresponds to a core group access point that is in the peer cell. Use one or more peer ports or one proxy peer to define the communication settings.

      • Peer port - Each peer port identifies a bridge interface of a core group bridge in the peer cell.

      • Proxy peer - A proxy peer is used to identify the communication settings for a peer access point that cannot be accessed directly through peer ports. A proxy peer specifies a peer access point that can communicate with the destination core group. The specified proxy peer must be a peer access point that has defined ports.

• Tunnel access point group - A tunnel access point group defines the core groups residing outside of the firewall.

  • Core group - Specifies a core group that is in this tunnel access point group. These core groups are referenced by core group tunnel access points.

    • Core group access point - The core group access point defines the set of servers that provide access to the core group. Bridge interfaces define the servers in the core group access point.

      • Bridge interface - A bridge interface defines a node, server, and chain for the core group access point. The chain defines the transport channels that the server uses for receiving information. Typically, all the bridge interfaces in a core group access point use the same chain.

        Avoid trouble: The bridge interfaces listed in the display tree on this page are listed as *,port. The asterisk symbol represents the multi-home support for DCS instead of a specific hostname.

    • Tunnel peer access point - The tunnel peer access point defines the set of servers, residing outside of the firewall, that provide access to the core group. Bridge interfaces define the servers in the tunnel peer access point.

      • Bridge interface - A bridge interface defines a node, server, and chain for the core group access point. The chain defines the transport channels that the server uses for receiving information. Typically, all the bridge interfaces in a core group access point use the same chain.

        Avoid trouble: The bridge interfaces listed in the display tree on this page are listed as *,port. The asterisk symbol represents the multi-home support for DCS instead of a specific hostname.
