[j-nsp] Re: M5 - outbound load balancing

[Fouant, Stefan A]

Hi,

Why don't my responses fall under the appropriate threads on the
puck.nether.net web site?  Should I change something on my email client?
Thanks,

Stefan

Hi,

Problem is here that BGP is making the decision as to which route to make
active (in the Local-RIB) and then sending that single route to the routing
table.  So from the routing table perspective you don't' have multiple
equal-cost paths to choose from, hence the load-balance per-packet policy
does not work.

You might want to try BGP multipath.  Can we see your configuration under
[protocols bgp]?

I tried the per-packet policy but it don't think I have it setup right.

A show route 65.0.0.1 shows me two equal paths

net.0: 151671 destinations, 302507 routes (151522 active, 0 holddown, 321
hidden)
+ = Active Route, - = Last Active, * = Both

65.0.0.0/19        *[BGP/170] 1d 00:43:22, localpref 100
                      AS path: XXX XXX XXX XXX I
                    > to 1.2.3.4 via t3-0/0/1.0
                    [BGP/170] 1d 00:43:28, localpref 100
                      AS path: XXX XXX XXX XXX I
                    > to 5.6.7.8 via t3-0/0/0.0

But a show route forwarding-table destination 65.0.0.1 shows me only one
destination

Routing table: inet
Internet:
Destination        Type RtRef Next hop          Type Index NhRef Netif
65.0.0.0/19        user     0 1.2.3.4      ucst    25 101673 t3-0/0/1.0

What am I doing wrong?
