Depends on what you mean. The RR has to speak VPNv4 routes so it can reflect them. If the RR is in the forwarding path, then it also needs to speak LDP/RSVP to pass VPN traffic; this is not a requirement if you won't send actual traffic over the RRs. > Does this RR have to be > MP-BGP (not the regular ipv4 BGP) or does it have to know vrf?

RRs need to know about all* the VPN routes in the core, so they can reflect them; PE routers only need to know about routes connected to them. *'all' is a bit of a misnomer; there's ways to partition RRs so that no single RR needs to have all the VPN routes. > Please share with me some info about this, I have all configuration and > output of several show commands(like "show ip bgp vpnv4 all) if you want to > see more. I have been told that mpls-ops should not be vendor-specific; try cisco-nsp if you want to go into cisco-specific details. > I'll appreciate if you have a sample working config to share with. > regards, See Jim Guichard's book on MPLS VPN. eric ------- The MPLS-OPS Mailing List Subscribe/Unsubscribe: http://www.mplsrc.com/mplsops.shtml Archive: http://www.mplsrc.com/mpls-ops_archive.shtml
