ibgp-multipath works only for core bgp routing instance v4/v6 routes, not for vpn routes.<br>you have to use ecmp in the vprn combined with different RDs being advertised within the core.<br><br><br><br><hr id="stopSpelling">Date: Tue, 27 Apr 2010 12:11:19 +0800<br>From: luthfis_mail@yahoo.com<br>To: alcatel-nsp@puck.nether.net<br>Subject: [alcatel-nsp] iBGP-multipath configuration<br><br>

The idea is I want to load share VPRN traffic within MPBGP cloud, and there are 2 objectives :<br><br> a. All VPRN (VRFs) will use ibgp-multipath<br> b. Only few VPRN (not all) will use ibgp-multipath<br><br>I've tried using command ibgp-multipath on global context and ecmp 2 on service VPRN context but still cannot get load balance result.<br>------------------------------------------------------------------------------------<br>A:ALu1>config>router>bgp#<br> enable-peer-tracking<br> family ipv4 vpn-ipv4<br>
