# neighbor default-originate

#### Syntax

[ route-map mapTag ]

{ no | default } neighbor { ipAddress | ipv6Address | peerGroupName } default-originate
[ route-map [ mapTag ] ]

#### Release Information

Command introduced before JunosE Release 7.1.0.
ipv6Address variable added in JunosE Release 8.0.0.

#### Description

Allows a BGP speaker (the local router) to send the default route 0.0.0.0/0 to a neighbor for use as a default route. When you issue this command in the route-target address family, BGP advertises the Default-RT-MEM-NLRI route (0:0:0/0). The no version halts sending a default route to the neighbor. The default version removes the explicit configuration from the peer or peer group and reestablishes inheritance of the feature configuration.

#### Options

- ipAddress—IP address of BGP neighbor
- ipv6Address—IPv6 address of BGP neighbor
- peerGroupName—Name of a BGP peer group. If you specify a BGP peer group by using the peerGroupName argument, all the members of the peer group inherit the characteristic configured with this command. You cannot override the characteristic for a specific member of the peer group.
- mapTag—Name of route map applied to modify the attributes of the default route or to filter the default route; string of up to 32 characters

#### Mode

Address Family Configuration, Router Configuration
