6.5 VPN Routing Policy (why we needed to originate default route into OSPF) ??

edited June 2017 in Foundation Lab 3


in this portion of the lab,

R4 generate default route and send it to R6,
R6 gig 1.46 is on vrf SHARED, and gig 1.216 is on vrf VPN_A
on R6 we redistribute BGP VPN_A into OSPF, all routes were redistributed except the default route

R6#show ip bgp vpnv4 vrf VPN_A
Network Next Hop Metric LocPrf Weight Path
Route Distinguisher: 100:100 (default for vrf VPN_A)
*> 0 65004 i
*> 0 0 65004 ?

but SW1:
SW1#show ip route
% Network not in table

SW1#show ip route
Routing entry for
Known via "ospf 100", distance 110, metric 1
Tag Complete, Path Length == 1, AS 2525, 2404, type extern 2, forward metric 1

we had to generate OSPF default route on R6 and send it to SW1,

router ospf 100 vrf VPN_A
redistribute bgp 6500.2525 subnets
default-information originate

whythe default routes was not redistributed into OSPF?
