PE-CE to serve Internet Connection to customer

Answered Question
Feb 7th, 2008

We have tenant in bulding to be connect to CE. From CE to PE using OSPF per VRF.

From PE (AS 1) to Data center Core SW (AS 2) ,we use BGP. And form Core SW to Edge Router (AS 3) using BGP.

My Questions are:

1) How to redistribute default route into BGP at PE. As right now, I need to configure one default route per each tenant(using VRF) and it is quite messy design. I think if we redistribute the default route into BGP, there are no need to configure default route for each customer.

Please help

I have this problem too.

To control the redistribution of a default route into the BGP, use the default-information originate command in address family or

router configuration mode. If the addition of this command does not resolve the problem, please send me the following output from both PEs:

show ver

show run

show ip route vrf 00102 0.0.0.0

show ip bgp vpn vrf 00102 0.0.0.0 0.0.0.0

show ip route vrf 00102

show ip bgp vpn vrf 00102
