Juniper BGP problem
« on: September 02, 2008, 03:09:53 AM »

Hi.
I have registered a BGP tunnel, but it does not work.
Platform is Juniper J4350 Junos 9
The example config tells me to use ip-0/0/0
The Forum says gr-1/0/0

When I use ip-0/0/0 or gr-0/0/0 I can ping myself but not the remote end.
When I use gr-1/0/0 I cannot ping myself either
I can ping the IPv4 address of the Ashburn router.
> ping 216.218.xxx.118       
PING 216.218.xxx.118 (216.218.xxx.118): 56 data bytes
64 bytes from 216.218.xxx.118: icmp_seq=0 ttl=254 time=4.384 ms
64 bytes from 216.218.xxx.118: icmp_seq=1 ttl=254 time=2.323 ms
64 bytes from 216.218.xxx.118: icmp_seq=2 ttl=254 time=1.330 ms

64 bytes from 216.218.xxx.118: icmp_seq=4 ttl=254 time=1.338 ms


My configuration (I do not know how much is public knowledge so I have censored a little)

   gr-0/0/0 {
        unit 0 {
            tunnel {
                source 93.93.98.1;
                destination 216.218.xxx.118;
            }
            family inet6 {
                address 2001:470:xxxx:f5::2/64;
            }
        }
    }

  Logical interface gr-0/0/0.0 (Index 72) (SNMP ifIndex 72)
    Flags: Point-To-Point SNMP-Traps 0x4000
    IP-Header 216.218.xxx.118:93.93.98.1:47:df:64:0000000000000000
    Encapsulation: GRE-NULL
    Copy-tos-to-outer-ip-header: Off
    Input packets : 0
    Output packets: 66
    Protocol inet6, MTU: 1476

      Addresses, Flags: Is-Preferred
        Destination: fe80::/64, Local: fe80::205:86ff:fe71:6700

BGP tunnels are done by hand, as such it wasn't up yet. It is configured now, and we cannot ping6 your side of the tunnel. As for the example config versus what the forums say, we've posted what our Juniper users have used that worked.

        }
        family inet6 {
            address 2001:470:xxxx:f5::2/64;
        }
    }
