Hi,
i need some help by configuring MP-BGP on Cisco ASR 903 Routers.
I have two Routers #Homer an #Bart they are linked via IS-IS on the transit-network. Each router has Access to the same VRF on differnet Subnetworks in different virtual Subinterfaces (on a ASR Router called Bridge-Domain).
The is-is works fine, the MP-BGP Informations a there but i can not ping from vrf test (10.10.0.0/24) on #Homer to vrf test (10.20.0.0/24) on #Bart.
BGP looks like good?!
