So i have this strange issue where i peer using BGP from UNL to a real router and exchange the NLRI. But if i advertise a prefix out from the UNL router to my real router when i try to ping it nothing... if i then jump on the UNL router and source a ping from that prefix my pings into UNL then work. Its almost like an ARP its so weird.

My real router sees this

111.111.111.111 via 172.16.21.198

My Laptop
-bash$ ping 111.111.111.111
PING 111.111.111.111 (111.111.111.111): 56 data bytes

64 bytes from 111.111.111.111: icmp_seq=88 ttl=64 time=11.719 ms

Any ideas? It works in GNS3 fine...

Thanks,

Ok this actually looks to be an issue when using VLANS on the Mac. If i pipe the Ethernet into the EVE environment it seems to work as expected. But if i use a VLAN interface on the MAC and bridge that into the VM then i get that weird ARP kinda issue. I will look at this and report back
