Index | Specifies the index of this peer group. The range is 1–1024.
GroupName | Specifies the peer group to which this neighbor belongs (optional).
Enable | Enables or disables the peer group.
RemoteAs | Configures a remote AS number for the peer-group in the range 0–65535.
DefaultOriginate | When enabled, the BGP speaker (the local router) sends the default route 0.0.0.0 to a group of neighbors for use as a default route. The default is disabled.
KeepAlive | Specifies the time interval, in seconds, between sent BGP keep alive messages to remote peers. The range is 0–21845 and the default value is 60.
HoldTime | Configures the hold time for the group of peers in seconds. Avaya recommends that you use a value that is three times the value of the KeepAlive time. The range is 0 or 3–65535 and the default value is 180.
Weight | Assigns an absolute weight to a BGP network. The default value is 100 and the range is 0–65535.
MaxPrefix | Limits the number of routes accepted from this group of neighbors. A value of zero indicates no limit The default value is 400 routes and the range is 0–4000.
NextHopSelf | Specifies that the switch must set the NextHop attribute to the local router address before it sends updates to remote peers.
RoutePolicyIn | Specifies the route policy that applies to all networks learned from this group of peers.
RoutePolicyOut | Specifies the route policy that applies to all outgoing updates to this group of peers.
UpdateSourceInterface | Specifies the source IP address to use when the switch sends BGP packets to this peer group.
RouteReflectorClient | Specifies that this peer group is a route reflector client.
SoftReconfigurationIn | When enabled, the router relearns routes from the specified neighbor or group of neighbors without restarting the connection after the policy changes in the inbound direction. The default value is enable. Enabling SoftReconfigurationIn stores all BGP routes in local memory (even non-best routes).
