Hello,
Please i need someone to clarify what is the difference between the
"default-originate" command and "network 0.0.0.0 - ip route 0.0.0.0 0.0.0.0 null0" commands.
I see both are serving the same purpose by advertising a default route to a peer but in the same time i feel a difference on them.
Thx
Regards,
A.M.

Peter, can you explain a scenario where you would use a
route map with the neighbor X.X.X.X default-originate?

Hello,
take the example below.
The default route to neighbor 10.10.10.2 is injected only if there is a route to 192.168.1.0.
access-list 1 permit 192.168.1.0
!
route-map DEFAULT 10 permit
match ip address 1
!
router bgp 1
network 10.0.0.0 mask 255.0.0.0
neighbor 10.10.10.2 remote-as 2
neighbor 10.10.10.2 default-originate route-map DEFAULT

Hi,
Thanks for the information, but i still have a little doubt, what is the difference between
default-information originate and default-information originate always ???

Hi Uttkap...
There is no such command in
BGP - default-information originate always"... this is for OSPF...
In OSPF the
default-information originate
will advertise a default route when such a route is present in the RIB
default-information originate always
will make the router advertise a default route regardless of the presence of a default route in the router - hence it ALWAYS originates a default route...
