The Virtual Router (BGP) – BGP Peer Group Setting page allows you to configure attributes for a Border Gateway Protocol (BGP) peer group. After you create a peer group, you can create and add members to the group.
This page supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) if you set the IPv6 environment variable. The first area of the page contains general parameters that apply to both IPv4 and IPv6. The second area is for IPv4 parameters, and the third area is for IPv6 parameters. If IPv6 is not enabled, the third area will not appear.
This procedure applies to both IPv4 and IPv6 if you set the IPv6 environment variable. Unless otherwise indicated, the descriptions of the user interface are the same for both protocols.
Enter the necessary information:
AS Number: Enter the asynchronous system (AS) number for the peer group.
EBGP Multihop: Select Enable to connect to the peer group through multiple, intervening routing nodes. Enter the number of hops for the connection to the peer group.
Keep Alive: Specifies the number of seconds between keepalive packet transmissions sent by the BGP routing instance to its peer.Select one of the following:
Use node default: Sets the keepalive transmission interval to one-third of the hold time.
Custom: Sets the keepalive transmission interval to the value you specify.
Hold Time: Enter the maximum number of seconds that can elapse between the receipt of successive KEEPALIVE and/or UPDATE messages by the local BGP routing instance or its neighbor. The minimum number of seconds allowed is three.
Retry Time: Enter the number of seconds following an unsuccessful BGP session establishment attempt with a peer that a session establishment by the BGP routing instance is retried.
Peer Authentication: Enter the MD5 password.
Force Reconnect: Select this setting to cause the peer to drop the existing BGP connection and accept a new connection.
Self as next hop: Select this setting to indicate that the next-hop value is the local BGP virtual routing instance.
Send Community: Select this setting to send the community to the peer.
Weight: Enter the value that indicates the priority of the path between the local BGP virtual routing instance and its neighbor. The higher the value, the greater the priority of the path.
Route Map: From the lists, select previously configured route maps for incoming or outgoing exchanges with the peer.
Click OK to save the configuration. Click Apply to continue configuring peer settings.
When you configure a neighbor, you can select the peer group to which the BGP neighbor belongs. See BGP Neighbor List.
