Subject: Doubts regarding VR based
VPNs
Hello All,
After reading draft-ouldbrahim-vpn-vr-03.txt and
other materials on VR based NBVPN i get the following
doubts:
1. Is it right to say that if we want to use
piggy-backing for VPN information discovery, the backbone VR configuration is
a must (because PEs have to be contacted by Public address which need not
be visible to the VRs).
2. Is it right to say that tunnels (MPLS,
IPSEC,etc) could be used only in the backbone VR based configuration because
otherwise the VRs have to be aware of the addresses and routes for
the PEs (public)?
3. Will the VRs send labelled packets to the
backbone VR? If so will there be any signaling (may be some registration)
between the VRs and backbone VR?
4. Is
it right to say that one VR can participate in only one VPN? (i did not
find details on multiple VPN support per VR)
Can somebody clear my doubts?
Please pardon me if these questions have already
been discussed.
Thanks in advance
Malick
