Hi All

Hope someonce can help me.  I am trying that traceroute 10.3.100.254 to from 10.3.100.100 on SW100.

SW100/101 i am not able to configure neighbor 10.1.13.13 additional-paths receive--- is that the issue?

Which IOS version i can use on SW100/101 to get that command running?

I am not getting multiple paths. I have completed all the config except ipv6 and multicast.

Can someone help me?

I use  "l2-adventerprisek9-m-15.2-IRON-2015*". You can not see some line in bgp section but it works.

Yes. i know on routers i cant see that command in running config even-though it takes the configuration.

Let me try iron image.

i am getting this

SW100#traceroute

So you can see only best route is there from RR on SW100.
