I have been through the documentation and the archives of this mailing
list and I'm at wit's end. I believe I've set this up so it should work
but it doesn't seem to EXCEPT when I ping with the route-record option
on. Then it works perfectly. Other traffic, such as plain pings, ftp
and telnet always take the same route.
This is the Junos config:
interfaces {
fe-0/0/0 {
unit 0 {
family inet {
address 10.10.152.253/24;
}
}
}
fe-0/0/1 {
unit 0 {
family inet {
address 10.10.153.253/24;
}
}
}
at-0/2/0 {
mtu 9192;
clocking internal;
atm-options {
vpi 15;
}
unit 15102 {
point-to-point;
vci 15.102;
family inet {
address 172.16.1.5/30;
}
}
}
routing-options {
static {
route 192.168.168.0/24 {
next-hop [ 10.10.153.1 172.16.1.6 ];
metric 1;
preference 150;
}
}
forwarding-table {
export load-balance;
}
}
policy-options {
policy-statement load-balance {
from {
route-filter 192.168.168.0/24 exact;
}
then {
load-balance per-packet;
}
}
}
FE-0/0/0,10.10.152.0/24 is connected to a Linux box which is my traffic
source. Fe-0/0/1,10.10.153.0/24 connects to virtual router A on an ERX
and at-0/2/0.15102 connects to virtual router B on the same ERX.
192.168.168.0/24 is an ethernet containing two Sun boxes which are my
traffic destinations and resides on virtual router B. Virtual router A
and B are directly connected with another ethernet.
This is the output of show route 192.168.168.0/24 extensive:
192.168.168.0/24 (1 entry, 1 announced)
TSI:
KRT in-kernel 192.168.168.0/24 -> {10.10.153.1, 172.16.1.6}
*Static Preference: 150
Next-hop reference count: 2
Next hop: 10.10.153.1 via fe-0/0/1.0

Is there something wrong with my config or is there a bug in this
version or what? Any help would be appreciated.
