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 ????

SOURCE PE WHERE IS THE ROUTE REDISTRIBUTED:

-------------------------------------------

pe1#

router bgp 4755

bgp router-id 10.10.10.103

no bgp default ipv4-unicast

ip route vrf B 0.0.0.0 0.0.0.0 Serial1/0 192.168.1.2 global <<<< STATIC ROUTE POINTING THE GLOBAL CONTEXT INTERFACE

!

DESTINATION PE HERE I CANNOT SEE THE STATIC DEFAULT ROUTE:

----------------------------------------------------------

pe3(config-router-af)#do sh ip bgp vpnv4 all

THE STAITC ROUTE IS REDISTRIBUTED TO LOCAL VRF CONTXT ASWELL AS WE CAN SEE:

----------------------------------------------------------------------------


pe3(config-router-af)#do sh ip route vrf A


Routing Table: A

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route


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

B 172.16.2.0/30 [200/0] via 10.10.10.102, 00:00:23

S* 0.0.0.0/0 [1/0] via 192.168.1.2, Serial1/0


Hope I am clear in explaining the issue...


Thanks,

Dara

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,
