[sistemisti]

Hi all! Based on this configuration/topology i want to advertise the BGP route on the default route and vice versa. Can somebody help me?

You have no BGP neighbours.  Who do you want to advertise a default route to?

Hi, thanks for reply! If you see my topology i want to be able to reach a host that it was in vlan to a host in vlan (in vrf). From now i see:

AS-SWCORE#show ip route
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 not set

C 192.168.56.0/24 is directly connected, Vlan5
C 192.168.94.0/24 is directly connected, Vlan6

Now if the host that have a 192.168.56.1 want to contact a host in VRF it's not possible now.

I want to make it possible in both way!
