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. Use this page to view the structure of your access point groups and tunnel access point groups.

.An access point group links core groups that are in the same cell or in different cells. The access points that are 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, you must also define a tunnel access point group, and at least one tunnel access point for each core group that resides 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 you are configuring communication between core groups that are in the same cell, configure an access point group with a core group access point for each core group in the cell.
- If you are 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 you are 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 that resides inside of the firewall, and a tunnel peer access point for each core group that resides 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 that is
configured to communicate with other core groups by using a particular
transport chain.
Best practice: Even though
it is possible to use a deployment manager as a core group bridge
interface, it is recommended that you use an application server that
is not a deployment manager.bprac

- Click to configure the settings for each access point group that is configured.
- Click to configure the settings for each tunnel access point group that is configured.
- Click to configure the tunnel peer access points for a tunnel access point group.
- Click to use one of the tunnel templates that are provided with the product, to define a tunnel access point group and the tunnel access points for that group.
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.gotcha
-
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.
- The core group access point defines the set of servers
that provide access to the core group. Bridge interfaces define the
servers that are in the core group access point.
-
Specifies a core group that is in this access point group. Core groups
are referenced by core group access points.- - Each peer port identifies a bridge interface of a core group bridge in the peer cell.
- - 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.
-
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.
-
Specifies a core group in a different cell. Define peer access points
to communicate with peer core groups.
-
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. 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.gotcha

- The tunnel peer access point defines the set of servers,
that reside outside of the firewall, that provide access to the core
group. Bridge interfaces define the servers that are in the tunnel
peer access point.
-
Specifies a core group that is in this tunnel access point group.
These core groups are referenced by core group tunnel access points.

that reside outside of the firewall.
