What is default-originate BGP?
The default-originate command is configured on a per BGP neighbor basis. This command artificially generates and advertises a default route only to the specific BGP peer. The default route does not need to exist in the Routing Table and it is not created in the BGP RIB.
What is originate in BGP?
The origin attribute indicates the origin of a prefix and can take three values: the prefix originates from an interior routing protocol (IGP), it originates from EGP, the predecessor to BGP, or the origin is “incomplete”, if the prefix is learned through “other means”.
How BGP distribute default route?
The static route needs to be redistributed into BGP by issuing the redistribute command. Inject into BGP by issuing the redistribute static command and configure the default-information originate command in router configuration mode.
What is passive interface default?
The Default Passive Interfaces feature simplifies the configuration of distribution devices by allowing all interfaces to be set as passive by default. In ISPs and large enterprise networks, many distribution devices have more than 200 interfaces.
What is the function of the default-information originate command in RIP?
default-information originate (RIP) To generate a default route into the Routing Information Protocol (RIP), use the default-information originate command. To disable this feature, use the no form of this command.
What kind of database does Alcatel Lucent router use?
Alcatel-Lucent’s router supports two databases for routing information. The routing database is composed of the routing information learned by the routing protocols. The forwarding database is composed of the routes actually used to forward traffic through a router.

Nokia (Alcatel-Lucent) BGP configuration tutorial. Part 1 – basic eBGP, iBGP Nokia (Alcatel-Lucent) BGP configuration tutorial. Part 1 – basic eBGP, iBGP There is no way I would leave you without covering configuration steps for one of the most versatile, scalable and robust internet protocols also known as BGP.
Which is BGP configuration guide for Nokia service routers?
And here it is – BGP configuration guide for Nokia (Alcatel-Lucent) Service Routers. As with the OSPF configuration tutorial I will cover the configuration process for various BGP scenarios along with the verification and troubleshooting steps bundled with colorful figures, detailed code snippets and useful remarks.
How does the BGP policy work on a router?
The BGP peering configuration process is simple, you saw it in Part 1, but, frankly, no network engineer leaves a BGP router in a default “receive all, advertise all” state. We use BGP policies to tell the router which routes to accept and which to advertise.
