I think you may be talking about ordered label distribution vs. independent label distribution http://tools.ietf.org/html/rfc5036#section-2.6.1
<http://tools.ietf.org/html/rfc5036#section-2.6.1>Cisco's implementation is independent where Juniper and maybe other vendors is ordered. Cisco will advertise a label for everything in its routing table regardless of how it learned it, where Juniper will only send a label for its connected loopback and everything else it received that is *already* labeled from the upstream. There is ways you can ACL bindings in Cisco so it only sends labels for what you need, but you can't change its implementation to ordered except for cell-mode MPLS. Rick, I haven't done anything with CsC but, are you sure there is one label per vrf? I am asking since it looks like Cisco can keep stats per prefix that is labeled, and the BPG labels on individual vrf routes are different: This are coming from the same PE: 7200-UT01>sh bgp vpnv4 unicast vrf vrftest 10.3.0.0/16 | in labels mpls labels in/out nolabel/525 7200-UT01>sh bgp vpnv4 unicast vrf vrftest 10.1.0.0/16 | in labels mpls labels in/out nolabel/657 On Mon, Feb 8, 2010 at 5:34 AM, Rick Mur <[email protected]> wrote: > Correct.
