Leigh,

 

For the default-information originate command to work you must make sure that they is a default route in the routing table. Also, you can use the default-information originate always command which does not follow the rule of default route in the table.

 

 
router ospf 10
network 5.0.0.0 0.255.255.255 area 1
network 6.0.0.0 0.255.255.255 area 0
default-information originate

ip route 0.0.0.0 0.0.0.0 6.0.0.3

All,

I'm having a little trouble sending a default route into bgp from ospf.

I have my ospf network (ospf ip 10) and my bgp network (bgp as 102).

My redistribution line in the bgp config is:-

router bgp 102
redistribute ospf 10 metric 1234 match internal external 1 external 2

I've got some loopbacks on one router going into ospf as E2 routes and
they redistribute just fine. I've put the "default-information
originate" command in to pass out the default gateway, but it does not
appear in the routing table of the bgp only routers.

Do I need to add in "nssa-external 2" into the ospf redist ?

Many thanks in advance.
LH
