GRT AND VRF Routing Leaking using OSPF

uni1389 · ‎10-23-2025

Hello All ;

I am trying to do Route leaking of Default route from GRT to MP BGP VPN4 and CPE having VRF OSPF instance as mentioned below but still am not able to do. I want to access internet from CPE35 . Below are some show output for your feedback and support.

Hello @uni1389

You could manually add a static default route into the VRF and redistribute it into MP-BGP ? The VRF defaut route will be announced to remote VRF sites via BGP VPNv4...

Best regards

Hi, check the following features/documents
- BGP Support for IP Prefix Import from Global Table into a VRF Table
- BGP Support for IP Prefix Export from a VRF Table into the Global Table

IP Prefix import and export works only with prefixes learned by BGP. You must have them in BGP table for import/export purposes.
In your case the default route in the global routing table is learned by ospf, not by bgp.
To make your configuration working, try to configure

!
router bgp 65000
network 0.0.0.0
!

this command will insert 0.0.0.0/0 into BGP if there is 0.0.0.0/0 in the routing table.

Then please check if the routing table on RTR-CPE35 vrf CUST-A contains the default route

RTR-CPE35#show ip route vrf CUST-A

If you will see a default route in the vrf routing table, this will be a good point. The default route should then be advertised using ospf 33 to RTR-CPE-33. Then try once again ping 192.168.0.1 from RR-CPE-33
