Hi,

I m trying to run BGP through the GRE tunnel, Tunnel is working fine.

*Though i  am seeing following error logs on bird.*

2015-09-07 20:29:34 <TRACE> vpn: Connecting to 10.200.206.250 from local
address 10.200.206.249
2015-09-07 20:29:34 <TRACE> vpn: Connection lost (No route to host)



*My bird.conf file has a follwing configuration for BGP through the GRE
tunnel.*

protocol bgp vpn {
local as 65530;
source address 10.200.206.249;
neighbor 10.200.206.250 as 65531;
import all;
}


*and following is the tunnel config on interface file, Tunnel is verified
and working pretty fine.*

auto gre-vpn
iface gre-vpn inet tunnel
    address 10.200.206.249
    mode gre
    endpoint 10.200.206.6
    dstaddr 10.200.206.250
    local 10.200.206.4
    ttl 255
    netmask 255.255.255.252


*Ping works*
root at fk-cloud-none-210121:/home/iaas# ping 10.200.206.250 -I 10.200.206.249
PING 10.200.206.250 (10.200.206.250) from 10.200.206.249 : 56(84) bytes of

64 bytes from 10.200.206.250: icmp_seq=3 ttl=64 time=19.4 ms



Please let me know what is the issue with the bird.conf here which i might
have missed.


Thanks,
Ajay
