UNABLE TO INJECT A STATIC DEFAULT ROUTE FROM PE????
Description:
I am unable to get a static default route via MPBGP session for a vrf, any other route redistributed the same way is getting through.
Just the static default route isn't ????

THE STAITC ROUTE IS REDISTRIBUTED TO LOCAL VRF CONTXT ASWELL AS WE CAN SEE:
----------------------------------------------------------------------------
pe3(config-router-af)#do sh ip route vrf A

Gateway of last resort is 192.168.1.2 to network 0.0.0.0
172.16.0.0/16 is variably subnetted, 5 subnets, 2 masks
B 172.16.200.0/24 [200/2170112] via 10.10.10.102, 00:00:23
B 172.16.20.0/24 [200/2297856] via 10.10.10.102, 00:00:23
B 172.16.10.0/24 [200/2297856] via 10.10.10.101, 00:00:23
B 172.16.1.0/30 [200/0] via 10.10.10.101, 00:00:23

Hope I am clear in explaining the issue...

Hi:
"Unfortunately" you HAVE to use the default-information originate cmd with BGP in addition to the static route.
:-)
Same goes for Ospf.....
A simple default static will not get redistributed !!
Regards.

Hehehe :)
"Unfortunately" that's true !!!!
This could have been the last thing that I try.
Getting he techs work, protocols work is fine.
But if get to make myself understand the logic behind adding this command as well than ... :(
Thanks a lot,
